gnuradio gets segfault in libexpat

Hi All,

i am using Gnuradio, which uses python and python uses libexpat. :-) My Gnuradio
programm has some graphical output using wx libraries, for example to show a
fft-plot or a scope plot. I have 2 PC's one works and the other get the
segfault. Both have the same OS(openSUSE 11.1). The segfault is:

Sep 11 12:08:26 linux-bqhl kernel: python[15201]: segfault at 8009 ip b45b9678
sp bfba7860 error 4 in libexpat.so.1.5.2[b45b6000+25000]

I do not know how to debug this further and get more information. Any idea ?

Maybe i am missing some libraries or some is broken.

Regards Markus
