Just to give completion to this ---<div><br></div><div>a backtrace with gdb showed the seg fault was actually in bgav_read_video () from /usr/local/lib/libgmerlin_avdec.so.1. Apparently at some point I built that for some reason instead of using the shared library that came with ubuntu Natty. When I switched to the one in the Natty repository, everything worked fine. So the problem had nothing to do with Gem.</div>

<div>Any video I try to load with [pix_film] causes a segmentation fault.</div><div><br></div><div>
To recreate, I load examples -&gt; 04.pix -&gt; 05.film.pd and click on any of the example video files to load. Instantly I get a segmentation fault. If I choose homer.avi the terminal window shows:</div><div>Pixelformat not specified for video frame</div>
