[mythtv-users] Lossless cut works from command line but not as user job

[Stephen Robertson]

I'm having a problem getting lossless_cut to work as a user job.  It's
run from the queue apparently successfully

But it completes straight away and there is no log.

Running the exact same command from a prompt works as the logged in user

stephen at bressay:~/mythgit/mythtv$ /usr/bin/lossless_cut -f
/media/disk/Recordings/9700_20121011072500.mpg -e -k

Copying "/media/disk/Recordings/Peppa Pig - S02E17 - The Long
Grass.mkv" to myth://Videos@bressay/Review/Peppa Pig - S02E17 - The
Long Grass.mkv

Running the job as mythtv user(which is what mythbackend runs as.
This is ubuntu/mythbuntu packages)
stephen at bressay:~/mythgit/mythtv$ sudo -umythtv /usr/bin/lossless_cut
-f /media/disk/Recordings/9700_20121011072500.mpg -e -k
[sudo] password for stephen:
Processing the configuration file failed. Error(The script does not
have read and write permissions for the "workpath" variables path:
"/tmp/lossless_cut")

So obviously there is something wrong with my permissions, but the
script seems to be returning success to the job queue.  As far as I
know I have not interfered with what the permissions are on /tmp/ from
the default.
