Bug Description

Binary package hint: mythtv

I have been testing Mythbuntu 9.10 for the past week or two and working with the folks in #ubuntu-mythtv on some issues. I am up to date on all packages as of the evening of October 21. (mythtv version 0.22.0~zrc1-0ubuntu1)

While playing around with lirc trying to get my remote tweaked, mythfrontend crashed on me. I had been using my remote and was watching a recording. However the stop/escape button on my remote wasn't working because of a lirc config issue (it wasn't mapped in the mythtv lirc config file) so I brought up the remote control in mythweb and clicked the "Escape" button. The screen went blank and I expected a listing of my recorded shows to re-appear. Instead it just sat there for maybe 15 seconds and as I was about to kill it via ssh, mythfrontend suddenly vanished and I was left at the Mythbuntu desktop. Unfortunately I can not seem to recreate this crash at will.

My goal was actually to restart mythfrontend to pick up the new lirc configuration so I wasn't really annoyed by it but when I mentioned it in IRC, Mario wanted me to test some crash reporting utilities (which broke launchpad with a 50 MB upload) so here I am!

Attached is the stack trace generated by apport-retrace of the file /var/crash/_usr_bin_mythfrontend.real.1000.crash

This is also happening to me when using the 'Escape' button on my MCE Remote to stop recordings. Each time the screen goes black, and the recording list does not appear.

Pressing 'Esc' on the keyboard exits the recording and displayes the recording list normally.

Changing the keybinding to something other than 'Escape' does not seem to have any effect and the problem still exists.

If recording finishes normally and exits back to the Recording List then Recording List displays normally.

While watching Live TV pressing 'Escape' on the remote works normally and the Main Menu appears without problem.

I've also noticed that if you use the remote for anything (change volume, pause etc) while watching a recording then mythfrontend will crash if you stop the recording with either the keyboard or remote.

Howdy, and thank you for helping to improve Mythbuntu by opening this ticket. Unfortunately, this backtrace attached is not useful to the developers. Could you please open a new ticket after following the "basic backtrace" directions outlined here:

http://www.mythtv.org/wiki/Debugging#Debugging_with_Ubuntu_packages

The above process will result in new tickets being opened, so I'm going to close this one. Please ignore the "Invalid" wording - that is simply unfortunate wording.
