What steps will reproduce the bug?

Note "null/channels" just above the Icon Search. (I think we used to see "null" in one of the paths to $something in the grabber config as well, I'm not sure if it was ~mythtv or ~mythtv/.mythtv, but it looks from here like pretty much the same issue -- #976 perhaps)

How often does it reproduce? Is there a required condition?

What is the expected behaviour?

What do you see instead?

Additional information

BE running as mythtv, so I assume it's looking for ~mythtv/.mythtv/channels/

$ ps ux | grep mythback            
mythtv       879  0.8  3.8 3599196 73020 ?       Ssl  Oct17 844:33 /usr/local/bin/mythbackend --quiet --syslog local7
mythtv    566449  0.0  0.1   9212  2432 pts/3    S+   12:20   0:00 grep mythback
$ ls -ld ~mythtv/.mythtv/channels/     
drwxrwxr-x 2 mythtv mythtv 12288 Dec 26 03:48 /home/mythtv/.mythtv/channels/

I probably should try to stay more up to date if I'm going to be making reports on master.

Based on the comment in #976, I checked that mythtv has $HOME set.

I also exported MYTHCONFDIR=/home/mythtv/.mythtv in ~mythtv/.kshrc (Yes, ksh, not bash) and that did not help.

Then, with MYTHCONFDIR still set, I stopped mythbackend via systemctl and started it again without that systemd nonsense. That worked.

Select an icon from directory "/home/mythtv/.mythtv/channels" for this channel.

Clearly the fix is to upgrade to Devuan

I see the same problem in master running as a systemctl service. I will fix it.
