-- Information about the crash:
- What I was doing when the application crashed:

VLC playing fullscreen on a second monitor handled by twinview.  The little VLC play/pause/stop control bar that appears in fullscreen mode was set to appear on my primary display.  I right-clicked on the VLC tile on the panel, "Move to Desktop > All Desktops."  Plasma crashed and restared.  VLC was not successfully moved to all desktops.

Desktop effects active.
