Comment # 11 on bug 979265 from Enno Nagel

With

  Exec=krusader -caption %c

or

  Exec=krusader -caption "%c"

or

  Exec=krusader %i

in

  /usr/share/applications/kde4/krusader.desktop

Krusader fails to start under Awesome WM. There's no error message, but simply
Dolphin opens. (With Exec=krusader, Krusader opens).
