Description (last modified by paulh)

I am running MythTV 0.28-fixes (up to 370dd71 which is current at this time.) Ubuntu 14.04 LTS (Trusty Tahr.)

I start the frontend, play a video, press e to begin commercial editing, press z to load the cut list, begin pressing right-arrow to advance through the video, and the frontend segfaults. Happens every single time on multiple recordings. As a result I cannot edit them. I can provide copies of the recordings if it would be helpful.

Replying to jason@…:

... if it would be helpful.

You should perform the steps as documented at https://www.mythtv.org/wiki/Debugging to provide a useful backtrace for the devs. As stated, you will likely need to install the debug-enabled packages to provide useful information from the core file.

Very well. I have recompiled it using --compile-type=profile and have attached output.txt with what it provides.
