Ciao Marcel,

How is it going?
there have been few commits  in the last 2 months touching the  
localization module.
If this input is working with an old version (3 months ago) of cp2k  
very probably a bug was introduced recently (not present in the  
regtest)..
Can you help us in tracking the bug?

The first thing to do is to try a version dated 2007-12-19.
For doing that you've to do a CVS update:

[..] cvs.berlios.de:/cvsroot/cp2k co -D2007-12-19 cp2k

or if you say that it was working in octover just try a whatever  
october day: something like 2007-10-10

you will get an updated version at the 19th of December..  Can you  
please check if with that one your input file is working?
Let me know in case we can proceed together in tracking the problem.  
How long do you need to run this input to see the problem?

Wait for your news!
Ciao,
Teo
