I got a ton of those:
Couldn't find backend for:
                           : " "
messages. I did a myth.rebuilddatabase.pl and added in some
shows that had been deleted from the database in the past. It
kind of worked, but I think it screwed up some fields in the
database that caused some of the slowness. I had about 20
entries with NULL in the recordid field. I deleted all of those
entries from the database and that got rid of the
Couldn't find backend for:
                           : " "
I still had a few errors but it listed .png files. I replaced those with
working .png files and that got me down to 2 seconds.
