Picard 0.16 "Scan" function isn't working in Ubuntu 12.04 ("Lookup" function works fine though, see also: https://bugs.launchpad.net/bugs/959582).

It produces errors like this:

E: 140580348659456 20:29:23 Network request error for http://ofa.musicdns.org:80/ofa/1/track/: Error downloading http://ofa.musicdns.org:80/ofa/1/track/ - server replied: Invalid "cid" (QT code 299, HTTP code 400)

Scanning & fingerprinting powered by AcoustID instead of the (default) AmpliFIND results in the similar errors.

Tested affected Picard versions: 0.16-2 (from official Ubuntu repositories) and 0.16+bzr1217~ppa6~precise1 (from MusicBrainz stable PPA).

Picard 0.16+bzr1281+53~ppa6~precise1 (from MusicBrainz daily PPA) is not affected, scanning (powered either by AcoustID or AmpliFIND) works fine.

I've been running 12.04 for almost a month, and have not had any problems fingerprinting in Picard. I've seen a very few of these Invalid "cid" (QT code 299, HTTP code 400) errors, but all have been cases where the MBID returned by accoustid identified a recording which no longer exists in MusicBrainz (ie, files tagged to now-merged releases, where the file was tagged with the old mbid back when we didn't preserve them post-merge.)

Note, this is running both Picard from the repo and Picard built from a github daily.

I think there was a problem with the newest QT which meant it needed to be compiled from github. Try doing that, it should work.

This was fixed some time ago (as you can see from the PPA package working fine):

https://github.com/musicbrainz/picard/commit/f3e6cde19fc2fbd9843e904772aded0a07364015

The problem was caused an incompatible API change in Qt 4.8 and newer.
