Comment (by paulh):

 I've seen this myself but very rarely its very unpredictable. The one time
 I got a BT it looked similar to yours though.

 Looks like its a problem with the LCD object. You could try disabling the
 LCD to see if the problem goes away to verify that. I'm wondering if maybe
 two threads are trying to update the LCD at the same time. One thing that
 has changed recently is the channel progress on the LCD is updated more
 often now. Changed from once every 60 seconds to once every second which
 makes it more likely that a clash will occur.

 If you could change the #define at the top of lcddevice.cpp to
 {{{
 #define LCD_DEVICE_DEBUG 10
 }}}
 and recompile then rerun mythfrontend and attach the last part of the log
 just before the crash it may help to figure out what the LCD was doing
 just before the crash.

 Also do you only get the segfault during live TV and not while playing
 back a recording?
