            Bug ID: 316640
           Summary: Network-Manager crashes in loop when enabled IPv6
    Classification: Unclassified
           Product: kdelibs
           Version: unspecified
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: kded
          Assignee: unassigned-bugs at kde.org
          Reporter: a.e.brownlee.iv at gmail.com

Application: kded4 ($Id$)
KDE Platform Version: 4.10.1
Qt Version: 4.8.4
Operating System: Linux 3.8.0-12-generic x86_64
Distribution: Ubuntu Raring Ringtail (development branch)

-- Information about the crash:
When enabling IPv6 on wireless connections Network Manager Applet starts
crashing in a loop which kills all connections. Removing IPv6 from the
connection stops the crashing, but a reboot is needed for the Applet to display
properly. Using Ubuntu 13.04 this was not a problem, so it seems isolated to
KDE.

The crash can be reproduced every time.

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