SIGSEGV on livetv rewind.

[anonymous]

Tried this on three different machines with different hardware each. One Master Backend/Frontend combo, one Slave Backend/Frontend combo and one Frontend only. Same results. Running latest SVN

You start watching livetv and then rewind. When you get back to the beginning the Frontend crashes with a SIGSEGV.

GDB backtrace and mythfrontend --verbose playback follows. Nothing of interest on backend logs.

Mythtv start live tv, then rewind to beginning causes SIGSEGV
