A skiplist database is corrupted.  This is not supposed to have *anything*
to do with sasl, so if you really did get it because of sasl, we have a damn
big bad bug that corrupts the application's stack/data space/open files.

And since skiplist has nothing to do with berkeley DB, it should not happen
because there are two versions of berkeley DB linked to cyrus imapd now,
either...  Still, that's a possibility.

Does downgrading fix the issue?  You may have a corrupted skiplist database
for other reasons, after all...
