Hi , There is debugging information missing from the bug report.
Could you run the following command in a terminal which will launch cheese in debugging mode:

 GST_DEBUG=*cheese*:3 cheese -v 2>&1 | tee cheese-debug.log

After you reproduce the problem , close cheese and upload the file cheese-debug.log (as an attachment) to the bug report. [which will be created in your Home folder]. This will greatly help us in tracking down your problem.

OK, i did that and the log is attached.

This is a bug in libv4l , changing task

I'm having a similar problem to that reported by Kabel. Cheese freezes under Ubuntu 10.04 when I try to record video using a Microsoft Lifecam Cinema HD webcam. Debug log attached.

Status changed to 'Confirmed' because the bug affects multiple users.

I have the same issue with a different webcam.

I would like to add, that VLC fails to open the cam out of the box.
However, I found that the following command opens the cam just fine (only a few Input/Output errors, but the image is fine):

vlc -I dummy v4l2:///dev/video0 --video-filter scene --no-audio

Another way that makes it work in VLC (but not Cheese) out of the box is running:

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so

and then running vlc
This will output a bunch of errors, but the video works.
