=============================================================

There are three separate signatures showing up here but the stacks all look similar. It appears as though this is related to a new glib version on the Beta version of Ubuntu 14.04 (due out next month). I'm not sure there's something we can do here but I'm reporting the bug just in case.

Comment 1

[Benjamin Smedberg]

karlt is this something you could investigate?

Comment 2

[Karl Tomlinson (:karlt)]

Interesting that the libc offsets can be so different.
gtk_rc_parse_string should not be calling gtk_range_get_round_digits unless there is some magic in the rc file that i don't understand or if a virtual function table or pointer is corrupt.

If someone can reproduce, does switching to a different gtk2 theme make any difference?  What theme is in use?

Sorry, I'm not permitted to spend time on desktop Linux issues, but I'll install gtk+-2.24.22 on my system to see if I can reproduce.

Paul, can you see if you can reproduce this in an Ubuntu 14.04 install?

Comment 4

[Paul Silaghi, QA [:pauly]]

Ok, I've set up Ubuntu 14.04 on a AMD64 machine.
Are there any STR? By simply running FF 28/30.0a1 I don't get any crashes. Also, switching themes doesn't change anything.

> Are there any STR? 

Unfortunately not. All we know by crash-stats is that this is a startup crash occurring with users of Ubuntu 14.04, Linux Kernel 3.13.0-*, and libc 2.19. The majority of the crashes are actually using Firefox 28.0 but the build IDs don't seem to line up to any of our official releases. It might be that these crashes are coming from builds in some pre-release PPA.

Comment 6

[Karl Tomlinson (:karlt)]

I wonder whether these are Ubuntu builds.

Comment 7

[Mats Palmgren (inactive)]

I suspect these signatures are obsolete now.  I couldn't find anything equivalent on crash-stats.
