I have loaded the lyric plugin, and the plugin that gesses the song information by file name, I added a few hundred songs to the playlist, and started listening to the songs.

Loaded the lyric for my current song from lyric planet (i think), and when noatun switched to the new song, it crashed. 

Here is the stack trace that  the crash handler generated. I hope it helps. If you need more information, please let me know. Thanks.
