[Pkg-mozext-maintainers] Bug#787803: xul-ext-firetray: firetray loads in GTK3 symbols causing Icedove/Iceweasel hang

Package: xul-ext-firetray
Version: 0.5.7~1+dfsg-1
Severity: grave
Justification: renders package unusable

Icedove is completely hanging after a few minutes. Some investigating with GDB
shows GTK3 symbols in the stack being mixed with the GTK2 which
Icedove/Iceweasel use.

This is also seen in the console output just before the hang:

(icedove:26456): GLib-GObject-WARNING **: cannot register existing type
'GdkKeymap'

(icedove:26456): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0'
failed

(icedove:26456): Gdk-CRITICAL **: gdk_keymap_have_bidi_layouts: assertion
'GDK_IS_KEYMAP (keymap)' failed

Which is due to GTK3 being loaded into a GTK2 program.

As far as I can tell it's firetray that is loading in GTK3. The time this
failure started is also consistent with firetray getting an update. I did not
find anything hinting at GTK changes in the changelog, though.

Removing firetray makes Icedove work again.
