Bug 457596

SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***


STEPS TO REPRODUCE
1. Open Application launcher applet
2. Type -160 into the search bar 
3. Observe plasmashell become unresponsive

OBSERVED RESULT
The plasmashell becomes unresponsive, the system tray and all the widgets in it become unusable and the plasmashell process maxes out a cpu core, the overall system is still usable though , Meta + L still triggers the lockscreen, Apps can still be launched using shortcuts.

I have tried recreating this bug with krunner and with the search bar in dolpin, so far only the application launcher applet has this issue.

Note : no other integer, positive or negative triggers this bug, only -160

EXPECTED RESULT
That the calculator function of the application launcher applet could be used without triggering a crash
