            Bug ID: 320042
           Summary: akregator crash in QtCore on loss of network
    Classification: Unclassified
           Product: akregator
           Version: 4.10.2
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: rcoe at wi.rr.com

Application: akregator (4.10.2)
KDE Platform Version: 4.10.2 "release 1"
Qt Version: 4.8.4
Operating System: Linux 3.7.10-1.4-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
The system was idle.  Akregator periodically polls websites for updates.
The wireless connection on this computer sometime loses connectivity with
the access point.  
When coming back to the computer, the crash handler was showing.

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