users-admin crashed with SIGSEGV in gst_tool_commit()

[nitromofolium]

Binary package hint: gnome-system-tools

Tied to add myself to the "audio" group after jackd complained at startup that i should do just that.
After beiing asked for the password for 'root' (root user is enabled here), i seemed to be able to make the changes, however when hitting the button for commit, the app sigsegv'ed.
