After successfully building gnuradio 3.6.2 on ubuntu quantal quetzal 12.10 i get this error when launching gnuradio-companion :

address@hidden:/usr/local/bin$ gnuradio-companion

Segmentation Fault (core dump created)

I satisfied all the required dependencies with the build-gnuradio script by SBRAC. Any ideas to solve this issue, it never happened to me in any build of GNURadio from stable tarball. Do I have to install some other python package ?

Thank you in advance

Kind Regards
