Bug summary

tk hangs/crashes if windows are closed not in reverse order of opened. This happens in ipython shell.

I have no other issues with ipython, only with matplotlib.

Code for reproduction

%matplotlibtkfigure()frommatplotlib.pylabimport*ion()plot([0,1])figure()plot([0,1])# Then close Window 1.

Actual outcome

Window 2 becomes non-responsive.

Expected outcome

There should be no crash irrespective in what order windows are closed.

In some cases the shell hangs entirely, and the terminal window has to be closed (^C or^Z do not work).

Additional information

It happens 100% of the time.
