I have a few mp3s with ID3v2 tags that taglib ignores completely. Investigation showed that this is because they contains a few tags whose data size was 0. I've fixed this and submitted to upstream, but I've not heard a response for several days, so I'm submitting it here to fix gentoo at least. Reproducible: Always Steps to Reproduce:
Created attachment 67463 [details, diff] fix for 0length ID3 tags I have submitted this upstream, but there has been no response, so I've no idea if this is the right way to do this. I works for me (tested with _many_ mp3 files).
What's the link of the upstream bug?
Best I can do for you is: http://mail.kde.org/pipermail/taglib-devel/2005-September/000194.html Looks like they're working on it now, even if my patch wasn't quite right.
Ok, we will just stay with what upstream will release then.
