Attachment: assertion stack

bz: could you take a look at this assertion failure, thanks

Comment 3

[Boris Zbarsky [:bzbarsky]]

So the really interesting and relevant part of the log here ought to be:

05:14:29     INFO - PREEXISTING EXCEPTION OBJECT: 'undefined: undefined'
05:14:29     INFO - undefined:0
05:14:29     INFO - undefined

which is sadly not as useful as it could be.  There's an exception, but we got nothing useful off it.

That _might_ be because we ended up with a security wrapper, or it might be because some chrome code threw a non-Error object like it tends to do.  In any case, the assert is just telling us "someone running before me screwed up and left a dangling exception".

To find the someone, we need info about the exception, or an rr trace, or a way to reproduce or something.

I filed bug 1349690 on hopefully improving the logging, so if this happens again we can have a bit more data.
