system-tools-backends crashed with SIGSEGV in dbus_message_iter_append_basic()

[Emmanuel Pacaud]

Binary package hint: system-tools-backends

This crash happened after I've clicked on the "change" button for the account type option in the "users & groups" dialog.

I got a dialog telling the application failed to connect via dbus, then the crash report.
