Here's the output from gdb:

Any help you can provide would be appreciated.

Note that after I first completed this, I could not get the same
error...ekiga would run, but it wouldn't detect my camera.  I unplugged
the camera and plugged it back in, and reran ekiga (via gdb), and was
then finally able to make it crash.

Thanks,
Andy
