same crash happens often on my system but while it is tuned to a TV channel (ATSC Digital OTA Antenna) which has bad signal quality. Crash happens also when Alt+Tab switching between applications and back to MythTV when it is still tuned to a frozen TV channel.
Trying to hit Escape to exit TV mode back to main menu usually triggers the crash. -- You received this bug notification because you are a member of UBUNTU - AL - BR, which is subscribed to Mythbuntu. https://bugs.launchpad.net/bugs/1456438 Title: mythpreviewgen crashed with SIGSEGV in QMutex::lock() Status in Mythbuntu: New Bug description: After watching a Recording, I exited during the movie credits by pressing the 'Esc' button without pausing the Recording.
