            Bug ID: 373616
           Summary: KDE5INIT crashes for no apparent reason
           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: sanj at sanjaykaria.com
  Target Milestone: ---

Application: kdeinit5 ()

Qt Version: 5.5.1
Operating System: Linux 4.1.36-41-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

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

On my Dell XPS12 laptop, I had Firefox open, Chrome browser open and Kmail
open.  The system had suspended due to inactivity.  When I input my screen lock
password it opened up again with the crash dialogue right there.  I'm not sure
what other info to provide you for the moment.  Please let me know how to help
further.

The crash can be reproduced sometimes.

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