Bug description:
  After switching from Fedora to Ubuntu (17.10 and now 18.04),
  whenever I plug my Logitech QuickCam 4000 Pro USB webcam
  and I start vlc or any other camera capture program, the memory of
  the program increases to maximum, as a consequence the system halt
  and the only way out is to reboot the machine.
