Description Wonko 2011-11-09 13:14:12 UTC 
Version:           unspecified (using KDE 4.7.3) 
OS:                Linux

Akregator often crashes when I close a tab. I think this started when I upgraded to 4.7.3, it did not happen with 4.7.2. BTW, the Application Version dropdown list is missing version number 4.7.3.

Reproducible: Sometimes

Steps to Reproduce:
Just open some articles in tabs, and close them.

Actual Results:  
For about 2/3 of the tabs, Akregator crashes. It seems that when the session is restored at the next start, those tabs that made Akregator crash when closing them, will do this again. Those that did not crash Akregator, will not.

Expected Results:  
The tabs should just close.

DrKonqui says the backtrace is not useful. Here it is anyway. I'm a Gentoo user, so if someone tells me what stuff I should recompile with debug information, I can do that.

Same behaviour here with Akregator 4.7.3 came from Archlinux repositories.
