I'm still getting this problem with current SVN. I can't reproduce it 
consistently though. I don't have a backtrace, just a frontend log with 
important,general,playback. Here is the tail end with comments:

That is the end of the log, but after the recording ended, I think I 
said 'save so I can watch later' when I actually wanted to delete it, so 
I then deleted it, and then selected the 'Back/Exit' button, which is 
when it crashed. It did not deadlock, there is no mythfrontend process 
running, and I can restart the frontend and carry on without any 
problems. This is a combined FE/BE. I just now looked at my lircrc and I 
noticed I have the following defined:

begin
    prog = mythtv
    button = Off
    config = Esc
end

and

begin
    prog = mythtv
    button = Back/Exit
    config = Esc
end

my 'Back' button is using the Back/Exit code, but is it a problem having 
two configured as 'Esc'? Or is that just a red herring?
