Bug 222330

Application: akregator (1.6.0)
KDE Platform Version: 4.3.90 (KDE 4.3.90 (KDE 4.4 RC1))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-17-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
Opened a website in Akregator and clicking on a button caused an overlay to apear over the page with buttons. Clicking one of the buttons to make a choice and then trying to change tabs akregator crashed on me. The Overlay does not crash on the Main akregator tab but seems to allow more freedom when the same site is opened in a tab. 

The crash does not seem to be reproducible.

 -- Backtrace:
Application: Akregator (akregator), signal: Segmentation fault
