Nope -- the same occurs in the regular terminal, so it's not  
iPython's fault.

Also, although I though I remembered this happening with qt4 (as  
posted below), I do not seem to be able to reproduce this now..

Also, clearing and closing the figure works fine -- only clicking it  
away triggers the bug.

So:  Almost surely MPL, probably Tk, is my guess.
