Insight crash

Subject: Insight crash

I'm able to make insight crash by bringing up the watch window on a
variable and then re-running the inferior.  Sometimes I have to play
with it a bit to have it fail.  I don't have a very precise recipe I'm
afraid.

Stack trace appended.

I'm running on my RH 6.2 x86 box.
