If a Proxmox VE replication job failed with an error message of several lines, the Proxmox VE Replication service crashed with ValueError: '\n' not allowed in 'summary'. An example is the message No common base snapshot on volume(s) ..., followed by Please remove the problematic volume(s) ... on a second line.

The service now goes to CRIT and shows the full error message on one line.
