Removing it will cause all seen state to be lost, which is not a huge
tragedy, but not exactly desirable.

058C is an offset in hex. If you truncate the file at this point,
you should be able to proceed. Obviously, everything after that will
be gone, but in my experience, these error typically occur at the end
of skiplist files, so you probably won't lose much if anything.
Also, this user's mail probably looks quite odd, e.g., all new mail
is always unseen. Anyway, something like:
dd if=/imap/conf/user/O/inqarts.seen of=/imap/conf/user/O/
inqarts.seen.fixed bs=1420 count=1
and
mv /imap/conf/user/O/inqarts.seen.fixed /imap/conf/user/O/inqarts.seen
Make sure /imap/conf/user/O/inqarts.seen is still permitted correctly.

I understand that later version of Cyrus have fixed many errors in
the skiplist code...
