            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: panel-devel kde org

Hello,

here my setting:
-Panel is configured to sit on the top of my screen.
-I do have two physical screens connected to my computer.

What I did:
-Adding the Analog Clock widget to the panel as the most right applet in the panel. On my screen the order from the right is then:
          >Analog Clock
          >Digital Clock, the standard clock of the panel
          >all other things running in the panel

-Removing the Analog Clock from the panel. Now, there is some space where the clock was drawn. Therefore the Digital Clock is the most right applet (at least it should), but it is drawn with space to the right border.

-Right click on the Digital Clock and choose Digital Clock Settings crashes plasma.

Here is the backtrace:
