Bug description:
*** START SRU INFO *** 
This package causes GDM to crash as-is. The fix is to add a comment to the .desktop file. This is not fixed in Maverick, but the fix has been well-tested and will be included in the next Debian version of the package. slangasek on IRC said he didn't see a problem with uploading this without fixing it in Maverick first. 

** TEST CASE **
Install sugar-0.88. Switch to GDM. Select a user, and select "Sugar" as the session. 

OLD BEHAVIOR: GDM should crash, disappearing from the screen.
NEW BEHAVIOR: The option is selected. 

*** END SRU INFO ***
I installed Sugar, and the session is properly listed as an option from GDM, but as soon as I select that session with the combo box GDM immediately crashes. This does not happen for any other sessions and occurs all the time for me.

I poked through the system log and the following stood out:

Mar 19 17:30:45 dylan-netbook gdm-session-worker[1439]: GLib-GObject-CRITICAL: g_value_get_boolean: assertion `G_VALUE_HOLDS_BOOLEAN (value)' failed
Mar 19 17:30:49 dylan-netbook gdm-simple-slave[933]: CRITICAL: Cannot read specified session file: sugar.desktop

Mar 19 17:30:49 dylan-netbook gdm-simple-greeter[1477]: WARNING: error opening connection: Failed to connect to socket /tmp/gdm-greeter-CveyZvQE: Connection refused

The fact that GDM is crashing is being filed as a separate bug.
