Mahmoud, please, If you find a way to reproduce can you provide us a step by step test case.

Thank you in advance.

[Mahmoud Lababidi (lababidi)]

Hi Hilario,
Thank you for taking a look at the bug. I've never seen such quick bug
response time.

I could try to reproduce the error, but I doubt I can. It seems in general
firefox on ubuntu has been over-processing and using much memory, so those
might have been a factor somehow.

what did the stack retrace say the problem could be?

I'll do what I can to try and reproduce the error.

Thank you,
Mahmoud

Is this still an issue for you? We are trying to sort this issue and would like to know if this still happens.

If it can be reproduced, please describe the steps to do it.

Thanks in advance.

[Mahmoud Lababidi (lababidi)]

I'm sorry I can't reproduce it. I feel it's a minor bug. I'm sure
there are other bugs that would be more needed of your time. Thank
you.

Thank you Mahmoud Lababidi for your feedback.

We have not received any duplicates for some time. Thus, this crash was likely due to some unique plugin extension combination or has been fixed in the meantime. Please, reopen it at any time if you have more related info.

Thanks for your contribution. Don't hesitate to submit new crashes,

I'm seeing what seems to be the same issue on Debian. I can reliably reproducing it by trying to log into my bank (ABN AMRO NL)'s online banking service. Stacktrace attached.

[Alexander Sack (asac)]

finally we found a duplicate .... hilario, going master for this issue?

[raboof (arnouten)]

See also debian bug 367956: setting MOZ_DISABLE_PANGO=1 also makes this crash go away.

[Hilario J. Montoliu (hjmf) (hmontoliu)]

A master should be at least in confirmed state

[Alexander Sack (asac)]

no new dupes for a long time.
