Play back seg fault on input switch

[bernhart2002@…]

when switching inputs while watching live TV (in my case hd to sd) mythfrontend crashes about 60% of the time. I am running truck r26882 from the mythbuntu daily builds repo. Here is a copy of the log file. Sorry for I don't see where to attach a file. Please let me know if you need anything more.

No, please produce a backtrace as described in the above wiki page.

Per mark, this should be fixed in current trunk. If not, please re-open, but *not without a backtrace as described above*.
