SUMMARY
Moving KEmulator with keypad on crashes plasmashell.
DrKonqi blames kioslave5 (details in attachments)
Plasma also freezes while KEmulator's window is vibrating

Video: https://www.youtube.com/watch?v=vPXrHEQdFM4

STEPS TO REPRODUCE
1. Download KEmulator from https://archive.org/details/KEmulator103 (md5: eefaa521a919f203a87169e1342934f7)
2. Run KEmulator.exe with Wine
3. Go to "View" and select "Keypad"
4. Move KEmulator's windows until Plasma crashes

OBSERVED RESULT
Plasmashell freezes and restarts after moving KEmulator window for awhile

EXPECTED RESULT
Plasmasheel should keep stable and working normally while KEmulator moves keypad window without problems

From the trace, kioslave is being told to quit at this point.
I suspect it has nothing to do with plasmashell dying, but rather it is a symptom of it.

That still means we need a backtrace of plasmashell when it's frozen, please see: https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_with_GDB

I've tried using gdb but it returns me no trace
