What's really interesting me is that some of those failed assertions you posted showed up in 2006 for a completely different package: https://bugs.launchpad.net/ubuntu/+source/grip/+bug/41601 It makes me wonder if the GTK_IS_WIDGET hiccup is not Firefox's fault.
I failed that assertion a few times in Firefox also: ============================================================================== GCJ PLUGIN: thread 0x805e090: NP_GetMIMEDescription GCJ PLUGIN: thread 0x805e090: NP_GetMIMEDescription return GCJ PLUGIN: thread 0x805e090: NP_GetValue GCJ PLUGIN: thread 0x805e090: NP_GetValue: returning plugin name.

I also can't reproduce your result* on 32-bit Xubuntu Hardy. Could be cause it's the 32bit version bt I will try to remember to check under Gnome and such later instead of XFCE. ** The upload sites you guys link to do not generate anything out of place for me.. Naturally if I can't reproduce it under 32 bit then it strongly suggests that your supposition about it being related to that other bug is correct? If I can reproduce it I will try to attach some of this: https://wiki.ubuntu.com/DebuggingProgramCrash -- maybe that will contain something useful, maybe not So anyway all in all is I think that there is some other problem causing the GTK_IS_WIDGET assertions to fail - it's curious that I have generated those warnings but don't know how to replicate them.. Maybe it will turn into a second bug. I am a lay person and know nothing but yeah, I am bold enough to suggest that if some other program had been also failing this assertion then perhaps something might be unhinged in gtk or elsewhere?? Maybe a couple of things? I hope I don't get in the way... -- firefox - red x icons in upload dialogs https://bugs.launchpad.net/bugs/218635 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
