And a similar problem, when disk is full:

address@hidden:/home/star27back# rdiff-backup --check-destination-dir backup

Actually, rdiff-backup is a disaster in dealing with full disks:
looking at the size of rdiff-backup-data, a lot of space is used by
old increments. Unfortunately, rdiff-backup --remove-older-than fails
because no more disk space is available! So this leaves me with a
chicken and egg problem: I have to make free space, but to free space,
I have to remove old increments, which is impossible because the disk
is full :-(
