Bug#780444: libwebkitgtk-3.0-0: use after free: GLib-GObject-CRITICAL **: g_closure_unref: assertion 'closure->ref_count > 0' failed

[Tobias Frost]

Control: severity -1 normal

Hi Paul,

I have the feeling this is not grave. 
Please see https://www.debian.org/Bugs/Developer#severities for the defintions.
Or do if I miss something, then please clarify. 

Thanks!
