mythfrontend.real crashed with SIGSEGV in QMutex::lock()

[hellojoker]

Binary package hint: mythtv

I wanted to quit because I was wrong to select the language and this error has occurred.

I was wrong to select the language because the mouse cursor was not visible.

Howdy, and thank you for helping to improve MythTV and Mythbuntu by opening this ticket. I have linked this ticket to a related upstream bug. While this problem is annoying, it does not affect system operation at all.

Should be fixed no later than when 0.25 is released...

[Mario Limonciello (superm1)]

0.25 is in precise -> fix released
