Hello.

Not surprising, the crash happens when the display engine updates the tool bar, 
and the Gtk+ build handles tool bars totally different.
I think the backtrace you posted is wrong, it looks like a normal run.  The 
backtrace I get consistently is below.
The crash happens because of the abort in the SELECTED_FRAME macro:

#define SELECTED_FRAME()                                \
     ((FRAMEP (selected_frame)                          \
       && FRAME_LIVE_P (XFRAME (selected_frame)))       \
      ? XFRAME (selected_frame)                         \
      : (abort (), (struct frame *) 0))

FRAME_LIVE_P return false.  There is some timing issue here, but I dont easily 
see it yet.  Anybody got a clue?

        Jan D.
