            Bug ID: 333052
           Summary: kded4 crash from resuming from sleep
    Classification: Unclassified
           Product: kdelibs
           Version: 4.12.97
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: kded
          Assignee: unassigned-bugs at kde.org
          Reporter: mastermind202 at gmail.com

Application: kded4 (4.12.97)
KDE Platform Version: 4.12.97
Qt Version: 4.8.6
Operating System: Linux 3.13.0-22-generic x86_64
Distribution: Ubuntu Trusty Tahr (development branch)

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

kded4 crashes immediately after laptop is opened (causing resume).  Doesn't
matter if battery or AC powered.  Not sure if it matters but I have it prompt
me for a password everytime.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
