Hej there!
I am using PyPlot to draw onto a Tkinter GUI (in Python 2.6). Works fine,
but when I close the window (root.destroy()) PyPlot apparently crashes with
the error message "Fatal Python error: PyEval_RestoreThread: NULL tstate"
(error 0x40000015). All I found was http://groups.google.com/group/comp.lang.python/msg/8e6bbae27a99f6d3 this
but it didnt help, I am using matplotlib 1.0.0.
Some pointers would be great, I am still a rookie when it comes to
programming...
A little while back, we put out an important v1.0.1 release that addressed many issues with the various backends. While I don’t remember all of the bugs it fixed, it may have fixed that one. I would suggest installing that version and seeing if it work for you.

I am seeing the same error. This is with a clean install of Python 2.7,
numpy 1.6.1, and matplotlib 1.0.1 (all 32-bit versions running under a Win 7
64-bit OS). In fact, all I am doing to test this is to execute the
'embedding_in_tk.py' example that is on the examples web page, with the
button calls at the end of the script uncommented. Any attempt to use that
'Quit' button causes the NULL tstate error.
Any info on this would be appreciated. I'm not saying I'm an expert, but
given that this isn't working "out of the box," it appears to be a bug.
