Strange problem with videocalling on Skype. Installation of Skype passed unremarkably and normal calls working fine. But when trying to do video call turning on the camera of the partner causes closing of the session,with black screen flashing for a second displaying an error message in command line, then appearing the logon screen. After logon all programs are closed, but the opened before disk partitions are still mounted.
Sometimes videocall goes fine, and problem appears after 4-5 minutes. In some cases after some such "restarts"call can be done without interruption for more than half an hour. But the lasti time it was breaking each 5 minutes ofr 4 times in a row, so finally I have to switch to Windows.
What can be the reason? Maybe a problem with the camera driver, becouse crash happens only in my computer. The laptop is older one - HP Probook 4510s, with built-in camera. With the previous Ubuntu and Skype versions never had such problems Ubuntu 12.04 is a clear install after formatting the partition (due to unsuccessful upgrade to 12.10). Skype was installed trough Software center
