two problems with empty tabs

[Jos van den Oever]

Hello list,

I'm not filing this as a bug report, but if that's more appropriate, i can.
But the bugs are rather important, so maybe this is better.

Problem 1:
opening a new tab with ctrl-shift-N, causes the cogwheel to keep rotating. In 
other words, konqueror keeps trying to load some empty url.

Problem 2:
Pressing F2 (rename) in an empty tab causes a crash. I guess some pointer must 
be empty somewhere. Here's the interesting part of the backtrace.
