totem-video-thumbnailer crashed during copy of a dv camcorder file from
one hard disk to another (18GB). Nautilus stops copy this file and totem
and totem-video-thumbnailer doesn't respond anymore. I cannot kill them
with kill or killall. Only a reboot stops them (why i cannot kill them
as root?!?)

This message appears many times in the kern.log:
