Ubuntu Multimedia :: Rhythmbox Time Tags Wrong Using EasyTag?

I just used EasyTAG 2.1.5 under Ubuntu 9.10 to update the tags on my music files running on Rhythmbox 0.12.5, and now Rhythmbox shows that the runtimes (Time) of dozens of my mp3's are now 27:03:11. That means Rhythmbox thinks all those songs are 27 hours, 3 minutes, and 11 seconds long, which they are not. Some are now shown as 54:06:23. So far they are all playing correctly, but the slider at the top of the Rhythmbox window barely moves, making it difficult, if not impossible, to jump to different points in the songs. Nothing else seems to have been affected.
