Почему я не могу выполнить xfce4-диспетчера-электропитания?

На моем Compaq nc8000 у меня есть проблема при выполнении xfce4-power-manager.

The program 'xfce4-power-manager' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadName (named color or font does not exist)'.
  (Details: serial 365 error_code 15 request_code 150 minor_code 11)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

Что могло вызывать это, и как я зафиксирую его?
