I've been having this same issue for a few days now. It looks like it was an ABI compatibility issue in my case. I removed the package audacious-crossfade and now audacious works fine.
Looking through the repository now I see no package named audacious-crossfade so it's either an old package that got removed or one that I got from somewhere other than the standard repository. If you need to check which audacious packages you have installed you can check the output of: dpkg -l 'audacious*' | grep ^i I currently have audacious, audacious-plugins, and audacious-plugins-extra installed with no problems. -- Alex Malinovich Support Free Software, delete your Windows partition TODAY!
