Does this happen often? It should only ever occur if the page you were looking at when you activated the elements list disappears; e.g. you alt+tabbed and changed to a different page or the page refreshes. In this case, this is a duplicate of #589. Closing as such for now; please reopen if this is really frequent and provide example web sites.

Unfortunately I can't provide you with a list of websites; it's totaly random.
I can asure you, however, that the pages haven't refreshed at all since I've brought up the Elements list. This happens when reading my mail through the GMail interface, but as I said, for the most part it's totaly random.

Is the final line of the error (about the null context handle) always the same? If so, this definitely indicates that the document has disappeared since you activated the elements list. Otherwise, maybe there's a different error in other cases that we need to see. How often do you see this? Also, does this happen in 2010.1?

Sorry, I missed that in my previous reply.
No, this doesn't happen at all in 2010.1, which suggests that something has changed that causes thsi issue in a later snapshot.

I'm not sure if this is related at all, but I've also encountered errors when typing text into a form on a web page. I've pasted my log below, hope it's of some help.
Cheers.

You didn't answer my question above:

Is the final line of the error (about the null context handle) always the same? ... Otherwise, maybe there's a different error in other cases that we need to see.

How often do you see this?

The hasContentChangedSinceLastSelection error is unrelated, but FYI, it was fixed in 704f778.

Sorry for the long delay; I forgot about this ticket.
Unfortunately, this error can still be encountered on both my netbook running XP Home, and on my PC running Win 7 Home Premium 64-bit.
Even if I wait for a couple of minutes to ensure that a page has finished loading, when selecting for example a link in the Elements List, I get the error.
However, if I then bring the list back up, nine times out of ten that same link will activate.

No developer (and possibly no other user) can reproduce this at present, so it's going to have to wait until someone can. I've really tried quite hard to reproduce this; I use NVDA constantly on the web. I know this sucks for you and I'm sorry, but there's really nothing we can do about this until someone with development knowledge can reproduce the issue and figure out what's going on.

I'll ask the same question for the third time:

Is the final line of the error (about the null context handle) always the same? ... Otherwise, maybe there's a different error in other cases that we need to see.

Are you only seeing this in the elements list now? The ticket summary mentions just navigating on a web page as well.

Please set your log level to debug (NVDA menu -> Preferences -> General settings) and reproduce the issue. Attach that log to this ticket.

Sure, that's understandable.

I'm not sure; I've only managed to remember to send the log that once.

Only in the Elements List now, yep.

Please set your log level to debug (NVDA menu -> Preferences -> General settings) and reproduce the issue. Attach that log to this ticket.

Done, will attach log when issue comes up again. :)

I'm actually beginning to wonder if this is a regression; I can't recall seeing it in 2010.1 at all.
Changes:
Changed title from "When navigating through a website using Firefox or by selecting an item in the Elements List, NVDA produces an error" to "When selecting an item in the Elements List, with Firefox, NVDA produces an error"

Are you using braille by any chance? If so, do you have braille tethering set to review?

No, unfortunately not.

However, a couple of minutes ago I was fortunately able to re-produce this error.
I've decided not to attach the log; it's about 2 MB, but I've pasted all text from when I activated the Elements List, hopefully this info will help somewhat.

Looks like I've got another error.

What's interesting about this one is that the first time I activate the Elements list their are 162 elements, but the second time only 156 ...

Technical: It looks like watchdog is killing off calls made by the virtual buffer's isAlive property, making it report that the buffer is dead and thus killing off the buffer. The log seems a bit out of order though. I need ot add some logging for when buffers die.

Elliott, have you tried this in a snapshot since main rev 3807 or perhaps in 2010.2beta1? I made a change in b57de67 which might at least improve this.

I added logging for virtual buffer death. Please try this again with a recent main snapshot and provide a debug log if the problem persists.

Replying to jteh:

Will do. I haven't actually seen this problem in a while; it was mostly encountered on my netbook which currently has a dead hard drive, however when I get that fixed I'll see if I can reproduce.

Nothing from reporter in months and I can't reproduce.
