[rekonq] Crash on opening tabs after closing other rekonq window

[Johannes Zellner]

Hi,

since about a week, I encounter many crashes in rekonq after 
closing/opening/loadnewpage/...

It's at least on my box easy to reproduce.
- Open two separate rekonq windows and close one of them.
- Now try to open a new tab on the lasting window --> crash.

Attached are two backtraces:
rekonq-20090924.kcrash:	crash after opening new tab
rekonq-20090924-2.kcrash:	crash after loading different page in existing tab

For now I was not able to find the problem...I'm not aware of the flow within 
rekonq with separate windows.

It looks like it tries to access tabs in the closed window, which are not 
existing anymore.

Thanks,
Johannes
