Just to give completion to this --- 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.
