[FEISTY] firefox crashed [@IM_get_input_context] [@nsWindow::IMELoseFocus]

[Sam Williams]

I had just started firefox form the commandline. and decided that I needed to shutdown instead and restart from the panel. I hit the close button and was immediate greeted with following commandline message:

(Gecko:17971): GLib-GObject-WARNING **: invalid uninstantiatable type `(null)' in cast to `GtkWidget'

(Gecko:17971): GLib-GObject-WARNING **: invalid uninstantiatable type `(null)' in cast to `GObject'

(Gecko:17971): GLib-GObject-CRITICAL **: g_object_get_data: assertion `G_IS_OBJECT (object)' failed
Segmentation fault (core dumped)

I'm running Feisty Fawn and I have the following firefox packages installed:
firefox 2.0.0.3+1-0ubuntu2
firefox-dbg 2.0.0.3+1-0ubuntu2
firefox-gnome-support 2.0.0.3+1-0ubuntu2

I will attach a crash report once this report has been opened.
