[PD] pix_opencv pdp_opencv segfault

thanks for your prompt answers.

we updated to maverick and installed pd-extended and opencv (deb packages).
we now have a segfault with Gem (closing gemwin) and gridflow crashes
the OS (see "grdflow v4l2" thread).

it appears that the issue is related to fglrx driver and ATI video
card because the same setup on an old asus a6g works fine.
the machine is a thinkpad w500 (core 2 duo, ATI FireGL 5200, 2.6.35-24-generic).

the weird thing is that all openGL tests seem to work fine
(fgl_glxgears, glxgears, etc) but I'm not a specialist..

cheers,
_yvan
