            Bug ID: 398320
           Summary: konsole crashes sometimes when selecting or pasting
                    text while pressing shift key
           Product: konsole
           Version: 18.08.0
          Platform: Neon Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: kde-bugs at cyborgsociety.org
  Target Milestone: ---

Application: konsole (18.08.0)

Qt Version: 5.11.1
Frameworks Version: 5.49.0
Operating System: Linux 4.15.0-33-generic x86_64
Distribution: KDE neon User Edition 5.13

-- Information about the crash:
- What I was doing when the application crashed:

select or paste text in vim

(usually I work with vim and select or paste text while pressing shift key due
to changed vim behavior automatically switching to visual mode when not pessing
shift key)

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
