Reproducible: Sometimes




I'm not sure exactly what causes it to crash, I lock my screens, turn off my monitors, and if I leave it running, I'd have either ~1 or ~20 Dr Konqi dialogs. Somtimes the panel on the second screen moves to my primary monitor, and the wallpaper will be different on the secondary monitor (the default one)
I haven't had a plasmashell crash when the screen is actually unlocked
 ....but I'm having some issues logging into Dr Konqi for some reason to report this with Dr Konqi...
