Version:           unspecified (using KDE 4.5.85) 
OS:                Linux

In Konqueror, I use around 15 tabs. Some tabs use KHtml and others use Webkit engine.
When I stop my KDE session and restart it, Konqueror restores the tabs but, the content of tabs using Webkit isn't restored (even if the associated URL isn't lost).

Moreover, sometimes, several tabs using Webkit reminds the URL of the last accessed website (before stopping the KDE session) instead on the URL of their last content.
The problem exists also when I save a Konqueror session to restore it later.

Reproducible: Always

Steps to Reproduce:
1. Open several tabs using differents websites but using the Webkit engine
2. Close the KDE session (without quiting Konqueror)
3. Restart the KDE session


Actual Results:  
When the Konqueror window is restored, tabs using Webkit are empty 

Expected Results:  
Tabs using Webkit should restore (or reload) the last content
