Bug 172224

Version:           1.3.1 (using 4.1.2 (KDE 4.1.2) "release 44.2", KDE:KDE4:Factory:Desktop / openSUSE_11.0)
Compiler:          gcc
OS:                Linux (i686) release 2.6.25.16-0.1-default

I have enabled the close butto for tabs in akregator. For some reason also the articel tab has a close button. When you accidentally close the articel tab via this button akregator crashes reporducibel with the following backtrace:
