Tkagg segfault on standard examples

Hi all,

I am unable to use the TkAgg backend on opensuse linux 10.2 or 10.3?
The standard examples

embedded_in_tk.py
embedded_in_tk2.py

end up with a segmentation fault. In debugger, the following message is
reported

Program received signal SIGSEGV, Segmentation fault.

Current language: auto; currently c++

I've tried it first with the pre-built RPMs from the site

http://download.opensuse.org/repositories/science/openSUSE_10.3/i586/python-matplotlib-tk-0.91.1-3.1.i586.rpm

Then, I deleted it and built matplotlib using current version
matplotlib-0.91.2.tar.gz

On ubuntu, the above listed examples are running.

Similar problem has been reported earlier.

It seems to be some tcl/tk installation problem. Does anyone have an idea how
to fix it. Lot of thanks
