[Bug 336544] [NEW] Firefox with "gdk_window_get_user_data: assertion `window != NULL' failed"

[John McCabe-Dansted]

Public bug reported:

Binary package hint: firefox-3.0

Occasionally when playing "Pirates: Rule the Caribbean!" on facebook
firefox crashes without any warning. On the terminal I see:

-------------------------------------------------------------------------------

** Message: NP_Initialize
** Message: NP_Initialize succeeded
** Message: totemPlugin [0x7f55e5c11720]
** Message: Init mimetype 'audio/mpeg' mode 2
** Message: Failed to get the base URI

(firefox:23546): Gdk-CRITICAL **: gdk_window_get_user_data: assertion
`window != NULL' failed

(firefox:23546): GLib-GObject-WARNING **: invalid cast from `(null)' to
`GtkContainer'

(firefox:23546): Gtk-CRITICAL **: gtk_container_add: assertion
`GTK_IS_CONTAINER (container)' failed

-------------------------------------------------------------------------------

Above that I also see a lot of errors like:

Greasemonkey getFirebugConsole() error:
(new TypeError("chromeWin.Firebug is undefined", "file:///home/xp/.mozilla/firefox/gqs3rdag.default/extensions/%7Be4a8a97b-f2ed-450b-b12d-ee082ba24781%7D/components/greasemonkey.js", 392))

However these errors appear constantly and do not appear to be related
to the crash.
