PRIV frames are already supported in SVN trunk and soon-to-be-released
TagLib 1.6 (http://marc.info/?l=taglib-devel&m=125200930026215&w=2).

I think it is a known problem, but can't be fixed due to binary
incompatibility. The 1.6 release is last in 1.x series, the next
release will be 2.0 which can break compatibility. It can be fixed
there.
