Steps to Reproduce:
  0. Make sure the CD drive tray is ejected and K3b is not running.
  1. Tell K3b to close the CD drive tray.

Actual Results:  
  1.
Program received signal SIGABRT, Aborted.

Process Manager reports that K3b uses 7 MB of memory.

Expected Results:  
  1. K3b should close the drive tray.
