            Bug ID: 391506
           Summary: Konsole sometimes crashes on exit
           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: paulus at mymail.root.sx
  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:
- What I was doing when the application crashed:
Exiting konsole using kwin's close actions. Sometimes konsole has several tabs
opened.

- Additional Infos:
Updated to KDE SC 5.12.2 from Neon repository.
This is a USB bootable KDE neon workspace. This error only happens on any PC
with nvidia graphics card.
All konsole settings are in their default vanilla values, except for (of
course) window size and location.
Also, sometimes konsole uses 100% single core CPU after exit (after the window
is gone). When this happens, opening another konsole window still works
normally.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Konsole (kdeinit5), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
