            Bug ID: 347473
           Summary: continued days of plasma crashing after attempting to
                    upgrade to Plasma 5
           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: kevin.coonan at gmail.com

Application: plasma-desktop (4.11.17)
KDE Platform Version: 4.14.6
Qt Version: 4.8.6
Operating System: Linux 3.16.7-21-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:  I had removed all of the
plasma5/KF5 I could possibly part with the exception of one or two things I
needed to try LXQT/RazorQT (very nice, once they were tweaked--actually ran
properly )

- Unusual behavior I noticed:

- Custom settings of the application:

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
