v2.42b testing

I have a series of MP3 files that cause mp3tag v2.42 to crash. The files were created by SoundConverter from FLAC sources originally tagged by Picard (MusicBrainz) tagging application. v2.42b does not crash. These files do not appear to be defective. They play successfully in many environments.

Tested environments: Windows XP Professional and CodeWeavers CrossOver Pro 7.1.0 on Ubuntu 8.10.

Thanks for the improvements.
