Francisco, as I said previously (not sure if it was here), I'm not upset
with you or with anyone at all. It's just that lately I hear so many
people complaining that cheese doesn't work, I even read some rather
"expert" guy in the forums saying to newbies things like "cheese is
completely broken in intrepid".

Cheese is just a software that gives you the webcam images, but there is some 
sort of toolchain to make it work: we use gstreamer, gstreamer uses the 
video4linux api to access the device, the video4linux api interacts with your 
particular webcam driver.
So if something is broken in this chain users always see Cheese as broken and 
report us it doesn't work. But there is some great chance that cheese is not 
failing but something at a lower level is.
Since most of the late issues appeared with intrepid switching to 2.27 kernel 
and many development went on recently in webcam drivers the chance of some 
regression at kernel level is someway increased.
I'm still not sure if gstreamer is involved too, but it seems it's really an 
uvcvideo specific issue, so, maybe, they could be both related.

I don't think so, maybe there are different ways to reproduce it but all end up 
with the webcam locked in the same way.

Did you try all the different resolutions supported by your webcam with 
gst-launch?
There is an easy way to get a better idea about who's causing the bug:
Could any of you test cheese with a 2.26 kernel?

Yes, I'm a Cheese developer, thank you :). Again, I'm sorry if I
appeared upset (consider also that English is not my motherlanguage :P).
