Comment 32 for bug 131227

Thanks for your patch, I tested it, but I can still trigger the crash with:

$ notify-send lala ; sleep 5; gconftool -t string -s /apps/notification-daemon/theme standard ; notify-send lala; gconftool -t string -s /apps/notification-daemon/theme ubuntu; sleep 10; notify-send lala

(sometimes this needs to be run a couple of times). The backtrace:
