I've had this problem for a while. When launching an app from krunner, it happens that at times, for no apparent reason, it jumbles together the possible option. Icons are superimposed, are not painted or apps that are not relevant are shown.

I have included a snapshot. In this example I wish to start kvpnc. As you can see:

• The first icon position holds both the kvpnc icon as well as the cogwheel that says 'run kvpnc'
• the 2nd icon position says mplayer, which should not be there at all
• the 3rd icon position is empty

I have no idea what causes it and if it is specific for my machine, for debian or a krunner bug.

EDIT
Forgot the snapshot:
