Ew. Ok. No thanks. :-) I'll just stick with numpy 0.9.4 for now.
I appreciate the speedy response.

You'll have to recompile matplotlib against the newer numpy.

After upgrading to numpy 0.9.5 (numpy-0.9.5.win32-py2.4.exe) running the
following script causes a crash of python.exe:
-------------test.py-----------------
import pylab
----------------------------------------
In my .matplotlibrc file I have the following:
-------------
backend : WXAgg
numerix : numpy
-------------
Reinstalling numpy 0.9.4 fixed the problem.
Matplotlib version is 0.86.2-win32-py2.4
I also tried reinstalling matplotlib, but that didn't help.

Its difficult to say if its bug in backend_gtk.py, it depends on exactly
what your application is doing. You would need to post a minimal test
case that demonstrates the bug so we could see whats going on.
