Problem when adding LOCALIZE section

Dear all,

i am using the 2.0.0 Version from 08.01.2008 of cp2k (just sopt
compiled with ifort-10.0 and g95) and encountered a problem when i try
to localize the WF during a md simulation to write the wannier
centers. The Energy is calculated correctly, but the dynamics after
the first localization is screwed up and the simulation is no longer
stable. I checked against an older executable from oct. there it
worked without any problems.


Here is an input from the QS regtest (H2O-md.inp). Just need to add a
LOCALIZE subsection to reproduce the error for this minimal setup.

The section i have added is:

     &LOCALIZE
       METHOD CRAZY
       OPERATOR BERRY
       EACH_STEP 1
      &END LOCALIZE


Any suggestions what might cause this, or am i doing the localization
the wrong way?
