Can you still reproduce this bug in recent builds? I would assume it was solved by the work around internationalization. P.S. What is a "slim profile"?
Looks like a race similar to bug 1236347. "Slim profile" should have meant the affected profile with all add-ons disabled or uninstalled, maybe also preferences reset with safe mode.
