Comment 17 for bug 1876609

The following patch to gnubiff fixes this problem, without requiring a change to gnome-panel.

Fix bug Launchpad 1876609
"gnubiff applet crashes when mail is received signal 5 in XGetWindowProperty"

    Use g_idle_add instead of gdk_threads_enter / gdk_threads_leave
    so that gnome-panel does not need to call gdk_threads_init.

    I have not changed gnubiff.cc as it does call gdk_threads_init
    and not changed gtk_image_animation.cc as I dont quite understand
    what it is doing.
