OH MY GOD!! This is so f***ing crazy shit!

The duplicate entries were created by doing the following procedure:

* Have 2 browser tabs: (1) Edit tt_news (2) the record history
* Work a bit in (1) - everything perfect, when you look in (2)
* Do a rollback in (2) - everything perfect
* Do some changes in (1) - everything perfect
* Reload (!) the frame showing the history -> it does, what it's called to  
do by its GET parameters and AGAIN reverses the change:

Two days to find out that you mustn't reload the history frame :(

+1 by reading and testing for your patch
