Even after applying the above mentioned patch. The fact that the pool size
shows at 0 bytes on the status page (pool size is several gigabytes) probably
has some bearing.

This might be the same as
https://bugs.launchpad.net/ubuntu/+source/backuppc/+bug/1612600 in
Ubuntu. A fix for that is part of
https://patches.ubuntu.com/b/backuppc/backuppc_3.3.1-4ubuntu1.patch
We should try to reproduce the issue and see if the according hunks of
the Ubuntu patch fixes it.
Regards, Axel
