gdmsetup crashed with SIGSEGV in strcmp()

[Alex Lourie]

Binary package hint: gdm

I'm running Karmic Alpha 3, updated as of 5 minutes ago.

I started gdm-control-center, selected "Login Screen". The dialog was shown for split a second, and was gone.
The exactly the same happens if I select "Login Screen" from System->Administration.

Apport has provided the option of bug report.
