So you're getting this error simply with a search followed by a delete? Can you post the metadata.db file from one of your libraries and also the search that you are using.
I downloaded the 64 bit version and get the same result.

calibre, version 0.9.42
ERROR: Unhandled exception: <b>LockingError</b>:can't downgrade SHLock object

Traceback (most recent call last):

LockingError: can't downgrade SHLock object

search joke

The metadata.db file is 3 mbs so I've reported a calibre bug and added as an attachment.

Bug #1208470
