Comment 19 for bug 91229

1) You recompiled Amarok from SVN source but not taglib. TagLib 1.4 is quite old by now, and a huge number of bugfixes have been checked into SVN since then. The problem doesn't sound to me like it's an Amarok issue, because we just pull in the tags TagLib gives us. I'd recommend recompiling TagLib from current SVN and seeing how that affects things.
2) Are you using CIFS or SMB? In the past I had a lot of problems with CIFS, although I hear it's much better now. But trying it on both would be good.
