Problem with /dev/video0

Hi there

I've got a Macbook 5,1 and installed (and learned to love ^^) Arch on it. Recently i wanted to take a picture with my webcam, but cheese ended with a segmentation fault (I already took several pictures a few days before that and had no problem). So i tried to run it in debut mode with

cheese --gst-debug-level=2

which gave me

0:00:00.164485739  4952      0x1a9ef90 WARN                    v4l2 v4l2_calls.c:264:gst_v4l2_fill_lists:<source> error: Failed getting controls attributes on device '/dev/video0'.
0:00:00.164552699  4952      0x1a9ef90 WARN                    v4l2 v4l2_calls.c:264:gst_v4l2_fill_lists:<source> error: Failed querying control 9963800 on device '/dev/video0'. (5 - Input/output error)
Segmentation fault

I then installed gnome-media package to run gstreamer-properties. When I try to test video (in) it gives me a nice

Video for Linux 2 (v4l2): Failed getting controls attributes on device '/dev/video0'.

This might be in some way linked to http://bbs.archlinux.org/viewtopic.php?id=98903 but I'm not so sure about it.

Thanks in advance for any help
