I am not sure which package is cause of problem. Read what reportbug suggested me:
A package named 'v4l' does not appear to be installed on your system; however, 'video4linux' contains a file named 'v4l'. Do you want to file your report on the package reportbug found [Y|n|q|?]? Getting status for video4linux... Please enter the version of the package this report applies to (blank OK)
Querying Debian BTS for reports on video4linux (source)... No bug reports found. I think problem is in v4l (video4linux) but i am not sure if it is a package or a xorg module or a kernel module.
