First of all, thanks for the testcase!  I could reproduce the problem
easily and after some serious headscratching it turned out to be a
really miserable typo which I just didn't see earlier due to the usage
of a C++ parameter default.  I've applied a patch in CVS.  This will be
fixed in 1.7.2.


Thanks again,
Corinna
