Michal Rudolf(the polish translator) pointed me out of the usual (and easy) KDE
way of generating/updating .po files:
and Pedro Morais told me something about the usual merge function...

make messages
  scans the source code and generate a new po/krabber.pot file (a very well
  documented .po file template for a new language)
make merge
  inside the po directory updates each krabber.po file

usually I am doing this. but it is your job to translate the new strings:

open YOUR_LANGUAGE/krabber.po with an editor (like vi or kedit or ... )
use a search function and search for "" 
this is a new entry which needs updates....
NO PANIC: if you leave the entry "" krabber will show the original entry and 
	  not nothing("") !

THE CHANGELOG FILE IS OBSOLETE !!!!

thanks a lot Michal and Pedro !!!
