            Bug ID: 391643
           Summary: Konsole occasionally crashes when closing it
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: henningstone at gmx.de
  Target Milestone: ---

Application: kdeinit5 (17.12.2)

Qt Version: 5.10.0
Frameworks Version: 5.43.0
Operating System: Linux 4.13.0-36-generic x86_64
Distribution: KDE neon User Edition 5.12

-- Information about the crash:
When closing the program it occasionally crashes. The latest incident was on
version 17.12.2 when simply closing the application window with multiple tabs
open.
I've seen this kind of problem (same symptoms at least) on older versions
before.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konsole (kdeinit5), signal: Segmentation fault
