            Bug ID: 296818
          Severity: crash
           Version: unspecified
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: Akregator/Kontact Crashes When Accessing Feed
    Classification: Unclassified
                OS: Linux
          Reporter: rwklarin at gmail.com
          Hardware: openSUSE RPMs
            Status: UNCONFIRMED
         Component: general
           Product: kontact

Application: kontact (4.8.0)
KDE Platform Version: 4.8.1 (4.8.1) "release 483"
Qt Version: 4.8.0
Operating System: Linux 3.1.9-1.4-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:  When selecting or attempting
to delete feeds (regardless of the feed site), Akregator and Kontact crashes. 
Consistently does this even when selecting "Do Not Restore Session" in
Akregator.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
