Someone said that I had not included the initial part of the backtrace, so I have rerun and attached a full gdb session here. The actions I took to get this result was to launch mythfrontend, select TV, select Watch TV, let the live TV run for a few seconds, and press ESC which causes Mythfrontend to crash. This happens consistently.
Thanks in advance for any help or insight you can provide.
Mike
