            Bug ID: 301665
          Severity: crash
           Version: unspecified
          Priority: NOR
          Assignee: unassigned-bugs at kde.org
           Summary: Crashes after resume from Suspend-to-RAM
    Classification: Unclassified
                OS: Linux
          Reporter: zilvinas.valinskas at gmail.com
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: kded
           Product: kdelibs

Application: kded4 ($Id$)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

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

Waking up laptop from 'Suspend-to-RAM'. Sometimes crashes.  Does not happen
everytime. Most of the time Suspend-Resume works just fine.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault
