This error appears when starting webcamstudio from menu in Ubuntu (mav). I've 
added my user to the video group but error still appears.

Have you installed from the DEB package?

kernel headers are also installed but dmesg yields

Have you recompiled v4l modules or anything about your kernel?  I've seen this 
in the past where a custom v4l2, kernel module would prevent the loopback from 
working.

Same issues.
Standard 11.04 32bit install without any changes.

Hmm, I have another issue reporting problems with GLIB2.0...  Seems that you 
need to install the libglib-dev to make things work...  I've fixed this with 
the 0.57 beta 1 by adding a dependency.  Could you validate?

I'm happy to report that I no longer get this error. Unfortunately, I can't 
shed any light on how I got it to go away. I forgot about this app and recently 
loaded it up and error is no more.

Then will hope that is was an Ubuntu issue...
