Public bug reported:

Binary package hint: mythplugins

The /etc/cron.hourly/mythvideo script essentially just runs the jamu.py -MW script. The problem is that jamu.py should only be run on the master backend. When the mythvideo package is installed on a frontend only or slave backend the cron.hourly script is still created. When jamu.py runs, I get hourly spam from cron: "error (grandchild #PID failed with exit status 1)" but looking at the /var/log/mythtv/jamu.log gives several errors:
"Jamu must be run on a MythTV backend"
"With any -M option Jamu must be run on a MythTV backend"
The log continues indicating a host of other problems due to artwork storage directories not existing, etc.

I don't think that jamu.py should be run by cron on anything besides a
master backend. Perhaps the cron.hourly/mythvideo script should do a
check to determine what type of machine it is and exit if not a master
backend. Alternatively this bug could be pushed upstream and have a way
for jamu.py to exit silently if it is running from a script and the
error is "not a backend" (and more specifically "not a master backend" -
there's no sense having jamu run on a master backend and again on a
slave for the same videos).

On a side note, jamu.py should probably exit immediately when it's not
running on a backend. There's no need to complain about video
directories when it's already determined that the machine is not a
backend. This is really be a bug for the jamu maintainer, I only include
it here in case the right people see this bug for the mythvideo package.
