Bug ID: 457596
Summary: Typing -160 into the Application Launcher search bar
makes plasmashell unresponsive
Product: plasmashell
Version: 5.25.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: Application Launcher (Kickoff)
Assignee: plasma-b...@kde.org
Reporter: vosaj18...@5k2u.com
CC: mikel5...@gmail.com, noaha...@gmail.com
Target Milestone: 1.0
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
