Hello, let me try to explain this bug:

There is a directory checked in the selection tree. The _base_ of the tree is marked by a blue rectangle, so You can see that a sub folder has been checked.

This sub folder has been removed, e.g. by konqueror/file manager.

The blue rectangle indicating the _removed_ subfolder remains.

This could - as I imagine - get some problems - at the moment it does not bother, but maybe in future versions...

I stand ready for questions, in neccessary.

amarok.kde.org-forum@secondimpact.de for contact.

Cu all, VerloreneSeele

OK, this is how to get the blue box removed from the directory tree:

open in Your favourite text editor the file ~/.kde/share/config/amarokrc and look (most likely on the top of the file) for the section:

[Collection]
Collection Folders=/long_hard_road_out_of_hell/Media/Musique

Remove the proper lines or strings as You desire.

Problem "solved"
