  Ah, that explains it.  But what I did to produce this was just to start gmc
and right-click on a file; perhaps this indicates some brokeness on my end :-(

  Hmm, the is_a_desktop_panel member looks funny but that's all I can see.
Your call. :-)  [ I'm going to do a clean compile of gmc and see if that fixes
