Bug 340308

The whole KDE session, including Akregator was left running overnight. No load on the machine. Just powered with a few programs on the screen. This morn
ing, I found the "Sorry there was a crash" for Akregator. All the other programs and the KDE session itself are fine. This is very typical

The crash can be reproduced every time.



Reproducible: Always

Steps to Reproduce:
1. Start Akregator, read a bit, leave it alone
2.  Go away for some time
3. Come back and find it crashed


Expected Results:  
Akregator should not crash, especially without any user interaction

Application: akregator (4.14.1)
KDE Platform Version: 4.14.1
Qt Version: 4.8.6
Operating System: Linux 3.16.6-200.fc20.x86_64 x86_64
Distribution: "Fedora release 20 (Heisenbug)"
