It looks like your metadata file got corrupted somehow, and now
rdiff-backup can't ungzip it.  It's filename is
<dest-dir>/rdiff-backup-data/mirror_metadata.<time>.gz.  The corrupted
one is probably the most recent one.

One quick thing to try would be to move it aside.  However, you may
lose some metadata, for instance if you not backing up as root, you
will lose ownership information for that particular backup time since
the ownership is not also stored in the increments/mirror files
themselves.

More elaborately, you could try to patch it up yourself.  The metadata
file is a gzipped text file with a simple format.  But if it corrupted
it seems likely that the information may not be there to begin with.
