I just installed Ubuntu 11.10 about a week ago. Now Firefox randomly crashes at various times. I have Firefox 14.0.1, no add-ons except for what comes with the default package.

Firefox almost always crashes whenever I download a file. It can also crash at other random times when I'm browsing the web. I never see any kind of crash dialog. If I run it from the terminal, I see the message
 (firefox:10547): Gtk-CRITICAL **: IA__gtk_entry_get_text: assertion `GTK_IS_ENTRY (entry)' failed
KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = gtk-qt-application path = <unknown> pid = 10547

[1]+  Segmentation fault      firefox
I've run into at least one other (presumably) unrelated issue with gtk version conflicts (see this thread). Ubuntu (or maybe TDE) seems to have 2 versions of gtk installed. Trouble is, I don't know how to determine which one to uninstall without breaking things...

Any thoughts?
