zmu -d /dev/video0 -q -v: Error, failed to query crop /dev/video0: Invalid argument


When I launch
Code:
zmu -d /dev/video0 -q -v
I get the following error:
Code:
Error, failed to query crop /dev/video0: Invalid argument
I've tried to chmod 777 my web cam:
Code:
sudo chmod 777 /dev/video0
but the I was getting the same error.

However
Code:
zmu -d /dev/video0 -V 1 -q -v
is working fine in Ubuntu 10.04 Lucid:
Code:
Video Device: /dev/video0
