mythfrontend.real crashed with SIGSEGV in __memcpy_ssse3()

[MarcRandolph]

Failed to stop decoder loop (QMutex::unlock: mutex lock failure)

* Used Handbrake 0.9.5 to rip Firefly E01E08 using default high profile settings (1.7 Mbps) - worked fine.

* Re-ripped with bitrate set real high (17.6 Mbps). Video will not play back - it just dumps me back to mythvideo after a while of "Please Wait...". One time I pressed <ESC> while the "please wait" was up, and it went to a blank screen and hung instead. I repeated it a second time, although the second log did not mention the mutex lock failure that the first one did.

Semi-related note: I've also seen where mythfrontend almost seems to get into a state where it won't show certain videos... I can hear the audio, but the screen simply shows the background image for the theme. I remember seeing someone else reporting this behavior recently, but I can't find it right now. I'm less certain that I can reproduce this.

We really do appreciate you opening this ticket to help improve Mythbuntu, but it needs to be closed for a number of reasons. The biggest one is that upstream has moved on to a new version and believes this to be fixed. Could you please verify if this issue still exists in the latest version?

Please do not let the closing of this ticket dissuade you from opening a new ticket if this (or any other) problem occurs with the newer versions.
