Not sure what would cause that.

Did it try to regress at the beginning of the session after the failed
one?

It's normal for the mirror_metadata and other things to be corrupt
after a failed session (since they're only partially written) but they
should all be cleaned up during the beginning "regress" period of the
next session.

If the repository is already quoted then rdiff-backup will maintain
the quoting for backwards compatibility.  But if you start a new
repository with a new version (maybe just 1.1.1/ maybe 1.1.0) then it
should be (and stay) unquoted.
