Version: 1.0 (using KDE 4.3.4) OS: Linux Installed from: Debian testing/unstable Packages Collection configuration dialog: I have four collections defined under "Local collections". Click on the red cross to remove the first collection and confirm removal of the collection -> As second row of remove buttons appears, see screenshot. These buttons actually work, clicking on the last one (shown in the row of "Collections on Removable Media" is connected to the last "Local collections" collection.
Created attachment 39293 [details] Extra remove buttons in the collection manager after removing one collection.
This is another bug in KWidgetItemDelegate, which is pretty much broken for tree views. For 182753 I found a workaround, this time I did not (emitting dataChanged() does not help, we are already emitting layoutChanged()). This must be fixed in kdelibs. *** This bug has been marked as a duplicate of bug 187820 ***
Fixed with #187820
