Comment 7 for bug 452520

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:
