            Bug ID: 485155
           Summary: Konsole and Konsole KPart crash when using shortcuts
                    with Ctrl
    Classification: Applications
           Product: konsole
           Version: master
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: noahadvs at gmail.com
  Target Milestone: ---

SUMMARY
When I use a shortcut with Ctrl, sometimes I get a crash. I can reliably get
crashes from Konsole KParts in apps with main UIs like Kate and Dolphin with
Ctrl+C, Ctrl+D and Ctrl+L. Sometimes I can get Konsole or Yakuake to crash, but
usually not. Sometimes I can get Ctrl+Shift+K to crash Konsole or Konsole
KParts, but usually not.

STEPS TO REPRODUCE
1. Open Dolphin and its terminal panel
2. Focus the terminal and press Ctrl+C to send SIGINT

OBSERVED RESULT
Dolphin crashes

EXPECTED RESULT
Konsole and apps that use Konsole KParts should never crash
