Yeah, good question ...

I've now pushed fixes for the above two problems.

The DBUG crash was actually an existing bug (also seen even in 5.5 tree), just
for some reason it became much easier to trigger after my changes. And yes, it
occured mostly in rpl.rpl_corruption, so maybe it is the same one you saw,
should be fixed now.

The other problem was a wrong locking order seen sometimes in main.plugin,
should be fixed now also.
