It happened when I accidentally picked Debugger from Teams window.

Resolution: fixed
Status: in-progressclosed

Fixed in hrev43208. The debugger can't actually debug its own team directly since that would block itself from executing(one needs two instances of the debugger running in order to do that). This resulted in initialization of the debugger interface terminating early, which wasn't correctly being handled in its destructor, which is now fixed. However, this situation should probably be handled a bit better as far as user feedback goes, since right now, double clicking it will do absolutely nothing.

Two possibilities come to mind: 1) The team should be grayed out/marked not selectable in the Teams window, or 2) Double clicking it should present a warning to the user indicating that the team is not debuggable. I would prefer the first of the two myself, opinions welcome.
