           Summary: Akregator Random Crash
           Product: akregator
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: spiderbill at gmail.com


Application: akregator (4.7.3)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.8.0
Operating System: Linux 3.1.1-2.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
Akregator was runing with one tab open to browsing 
http://www.mysqlperformanceblog.com/2011/11/29/percona-replication-manager-a-solution-for-mysql-high-availability-with-replication-using-pacemaker

I went back to the feeds and opened in in an external browser ( firefox 8.0),
five seconds later, akregator crashed.  Maybe related to kwebkit? Don't know
really. It crashed in a simular manner yesterday, but the debug symbols
couldn't be installed correctly from the repos for some unkown reason.

-- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
