It seems that when GnomeMeeting starts the camera grabber, it makes your
driver crash. (You can see a problem, a kernel module crash in the last
part of the dmesg). If the kernel module of your webcam driver crashes,
it is normal that GnomeMeeting crashes. This is most probably a bug in
the kernel driver of the webcam, triggered by GnomeMeeting, but not a
bug in GnomeMeeting itself. You should contact the webcam driver author
and ask him to try. Perhaps he will know what to do, but in no case
GnomeMeeting should be able to crash a stable webcam driver.
