[Bug-gnupod] ArtworkDB: Unexpected artwork-mhod type: 6

[Richard van den Berg]

It seems my ArtworkDB got messed up today. I'm not sure why, but I
received this message:

$ mktunes.pl
mktunes.pl 0.99.9-DEVEL (C) Adrian Ulrich
> GNUtunesDB sync needed...

[cut]

After this no artwork is shown on the iPod. The weird thing is, I did
not add anything to my iPod for months. No mp3s, no artwork. I quickly
saved ArtworkDB.old and GNUtunesDB.xml.old to do some testing.
Interestingly, the ArtworkDB grew 300k after the mktunes run:

-rwxrwxrwx   1 richard  staff    1486544 Mar 24 08:34 ArtworkDB
-rwxrwxrwx   1 richard  staff    1177904 Jan 28 18:05 ArtworkDB.old
-rwxrwxrwx   1 richard  staff   44740000 Jan 28 18:05 F1028_1.ithmb
-rwxrwxrwx   1 richard  staff  178960000 Jan 28 18:05 F1029_1.ithmb

Using ArtworkDB.old I could trigger the issue every time. I finally
commented out the die in get_awdb_mhod() in iTunesDB.pm when an unknown
mhod is parsed. This seems to make everything ok again.

I don't have time to inspect the ArtworkDB right now, but I just wanted
to put this out there in case someone has the same problem.
