Public bug reported:
I clicked Edit->Preferences, clicked through a few tabs, then clicked
Applications. Firefox froze.
Here's the stack trace:

It looks like Firefox launched another process and was waiting for it to
exit - though I couldn't tell which process it was. (All of the
arguments in the stack trace were optimized out.)
I found all processes whose parent PID was Firefox:
23079 ? Sl 0:14 /usr/lib/firefox/plugin-container
/opt/google/talkplugin/libnpgoogletalk.so -greomni /usr/lib/firefox/omni.ja
-appomni /usr/lib/firefox/browser/omni.ja -appdir /usr/lib/firefox/brows
23456 ? Sl 2:02 /usr/lib/firefox/plugin-container
/usr/lib/flashplugin-installer/libflashplayer.so -greomni
/usr/lib/firefox/omni.ja -appomni /usr/lib/firefox/browser/omni.ja -appdir
/usr/lib/firefo
25393 ? Z 0:00 [sh] <defunct>
I'm guessing it's the last one. Maybe there's a race condition where the
process exits before Firefox starts waiting for it?
The bug only happened the first time, and I couldn't reproduce it again.
