[mythtv] More on Mythtv0.11 crashing with fast forward. backtrace from cvs gdb

[cmisip]

I installed the weekly cvs gdb 9/01/2003 and got this backtrace.  To
produce the error I pressed fast forward and when mythtv got stuck, I
pressed P to pause and P to play.  This seems to keep it from going back
to the Watch A Recording Screen.  Then when the disk thrashing quits, I
killed mythfrontend.   I dont know what else to do if this does not have
enough information.
