Hi Margar,
Philippe has already answered your mail.
I take, however, this opportunity to make once more a request
to people sending similar problems to make an effort to digest the
problem as much as possible and try to send a very short example.
We are spending an incredible amount of time in digging problems
in large tar files, where in fact the problem was simple to reproduce
with a few lines of code. In the vast majority of cases, the sender
discovers the problem himself in trying to prepare a short running
example.
