mythburn crashes only when called from within myth

[agoodm]

Here we have a very weird issue with mytharchive.

Basically if go through the onscreen (mythtv menus) process for creating a DVD I get to the log viewer and the process stalls after detecting the number of cpus my box has. This will leave an xml file in the config folder thats created in my temp folder - which is handy - see further down for why. After running mytharchive in this manner there are errors in the logs/mythburn.log file. These are appended to the end of this bug report.

The strange twist came when I tried running mythburn.py manually. I ran the following commands:
cd /path/to/tempdir/config
python /path/to/mythburn.py

This caused the script to run as expected with no issues and about 45 minutes later a dvd popped out which is perfectly functional, no issues what so ever.

Marking invalid as this release isn't supported anymore. Can anyone confirm that this issue is still present on a supported Mythbuntu/MythTV release? If so, feel free to reopen.
