I uploaded this earlier but then noticed some problems with the icon file so I had to fix it.
The gear is a reference to the KDE logo and the two gears together represent the dual panes of the Krusader file manager. I included the b&w and plain color version of the logo as required by the rules. I also included a glossy, eye-candy version of the logo as well, as a bonus. All the original svg files are in the archive.
Created in Inkscape.
