Status changed to 'Confirmed' because the bug affects multiple users.

I got this error also, when updating packages with synaptic :

Gtk-WARNING **: Impossible de trouver le moteur de thème dans module_path : « pixmap » at /usr/share/perl5/Debconf/FrontEnd/Gnome.pm line 97.

This bug not only affects Firefox, it affects other applications like Google Chrome, Chromium and the Software Center.

I confirm this also affected vmware-workstation, and possibly virtualbox too...
