Crash when closing last tab

[Allan Sandfeld Jensen]

Example: Start konqueror and enter any web-site with links. Select a link with 
a right click and choose "Open in new tab".  Then right click on the tab and 
select "Close tab". Konqueror crashes with the following backtrace:

Not very usefull, but since this broke recently. I hope someone knows what
