Cannot add KDE shortcuts to Unity launcher

Binary package hint: unity

On trying to drag-drop a shortcut to the BasKet Note Pads application from the application search menu, the operation appears to be recognised by Unity (i.e. when the icon is dragged over the the launcher, the icons move aside to accommodate the new shortcut). However, when the mouse is released to drop the shortcut onto the launcher, it does not appear and the existing icons move back to their original locations. On examination of the launcher, no shortcut to BasKet Note Pads has been added anywhere. On further investigation, attempting to add shortcuts for any other KDE application installed on my system results in the same vanishing problem while other GTK/desktop independent application shortcuts can be made.
