Public bug reported:
Binary package hint: rdiff-backup
Running version 1.1.5 (edgy). I sucessfully completed an initial backup
to a remote server via SSH. Later, I started another (incremental)
backup to the same destination. This was interrupted (probably due to a
network problem). Any subsequent attempts to perform a backup to this
destination result in the following stacktrace, which occurs soon after
starting the command (maybe 15 seconds or so):
Executing ssh -C backupserver rdiff-backup --server
Unable to import module posix1e from pylibacl package.

Fatal Error: Lost connection to the remote system
----------------------------------------
If I change the target directory to something different, then it works
again, beginning to backup everything from the beginning. It seems that
rdiff-backup should be a bit more robust against connection failures, so
as to allow a user to resume where the backup was interrupted from.
