The main problem is that TagLib uses non-thread-safe reference
counting on shared objects. Until this is fixed, you should not use
TagLib from multiple threads (yes, even on different files).

I'm not aware of any code in TagLib that would use STL iterators
across functions that could potentially get called from different
threads, so I don't believe that's the problem.
