whole server log in case it's needed.

I see this sometimes after a file that is listed in Zapped playlist is deleted.
 I think in the cases I've seen, it was the only file listed.  This is not
always reproducible.  I believe based on the scanner log that the scanner is
not running.  The hang can be cleared by aborting the scan with the web
interface.  The scanner log has not recent entries - last are my full scan in
the middle of the night.  The relevant server log entries are:
