Description Giampaolo Gallo 2002-12-13 09:24:04 UTC

Version:           2.2.0 (using KDE KDE 3.0.99)
Installed from:    Compiled From Sources
Compiler:          gcc 3.2.1 
OS:          Linux

trying to remove all the files lin the playlist causes noatun to hang.
It must be killed. Moreover, some artsd processes remain around and they must be  also killed, otherwise no more music (the audio device remains locked). I succeeded in removing all the files from the playlist by using a "1 at a time" approach.

Please kill the process with "kill -6" and post the result.

I fixed Playlist Item removal from SPL not too long ago.
