Version: 0.50.1 (using KDE 4.0.3)
Installed from: Ubuntu Packages
Compiler: gcc 4.2.3
When I'm trying to check the "Use specified media player" in configuration window, listbox with list of players doesnt become available. It remains grayed and doesnt respond on clicks/etc.
Hope this will answer on all the questions :P
Also it is strange what Kopete still doesnt have support for Audacious audio player.
For audacious, see (or vote for, if you like) bug 142643.
