taglib 1.7.2 was issued to fix a minor security DoS issue due to a divide by zero error in the MP4 file decoder.
I built it in updates_testing but I don't have an MP4 file to test it with. If interested people could test it, it could be pushed to updates. Thanks. (Note that this request is for Cauldron. For Mageia 1 there's Bug 5905.)
