            Bug ID: 362586
           Summary: Crash when plugging in HDMI
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: pascal at dhermilly.dk

Application: kdeinit5 ()

Qt Version: 5.5.1
Operating System: Linux 4.4.0-21-generic x86_64
Distribution: Ubuntu 16.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
The crash dialogs started appearing when I plugged in HDMI for a 4K TV.

If you keep letting it crash, at some point it freezes the computer (at least
longer than I wanted to wait.)

The crash can be reproduced every time.

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