            Bug ID: 350097
           Summary: Plasma crashes on login
           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: yannick.baro at gmail.com

Application: plasma-desktop (4.11.20)
KDE Platform Version: 4.14.9
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:

Trying to log into my session. Now happens about 3 times out of 4. Also, my
computer freezes often, I do not know if that issue is actually related but
when it does freeze, I am nearly certain I will get this bug afterwards.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Outil de gestion de fenêtres Plasma (plasma-desktop), signal:
