Sometimes instead of playing mp3 file, xmms creates a big wav file in my home directory and don't play anything. I tried xmms 0.9.5 and 1.0.1
It's selected the disk writer output plugin, most likely because of upgrades from versions that install into different directories (/usr/bin vs. /usr/X11R6/bin.) Either upgrade to the xmms currently in rawhide, or just reselect the appropriate output plugin in the preferences.
