Crash with musepack files and taglib 1.4

[Benoit Amiaux]

Hello,
I just updated taglib to 1.4 to see how it was working with 
(xmms|bmp)-musepack plugins.

I was using previously an svn version which had the memleak and empty 
genre tag bugs fixed. This version was working perfectly. Unfortunately, 
I don't remember which revision it was.

1.4 always crash.

One backtrace example:

I'll try to see what was recently broken..
