libpst-0.6.49-1.fc12 has been submitted as an update for Fedora 12.

This is fixed in libpst-0.6.49. No test-case exists (one would need to learn the pst format and to create the pst file with non-email objects manually).

The fix is trivial:

fix to ignore embedded objects that are not email messages
