mysterious error concerning page header / footer

CR2008

VS .Net 2005

I get the following error (I try to translate cause we have german runtime environment):

Page header and footer are too big for this page.
Error in file "Report ...{F8 ... 1DD} .rpt"
Page header or footer longer as one page.

As far as the report has an empty page header about 1 cm high and a footer with just the page number and the printing date within - as well 1 cm high it is difficult to get the reason why the error occurs ...

Fortunately (or should I say irritatingly) it happens not with all printed reports from that .rpt but at least with one issue - but I won't find out what data could be responsible for the error.
