I am working on the last releases of PyQt4 and Matplotlib (on mandriva
May be I'm tired but found a new problem .... the question looks trivial:

If I copy as a normal user the official example of embedding_in_gtk2.py
all works well as usual.
But with  "embedding_in_qt4.py" it is crashing with a segfault.

if I su Root and launch "python embedding_in_qt4.py" it works well !!

I can't understand what is different and it is a big problem when I promote
an mplWidget as QWidget.
(Not to say that I had no problem with  previous PyQt4 releases)
I did my best in really checking all environment :
.matplolib/matplotlibrc and matplotlib.conf
permissions in backends distrib directory ....

... no way ... root works and not serge ! have you an idea.
