This issue was observed by Teresa while working with the interactive macros.
Basically it is about the applying ranges of the Qt spinbox widget.
Seems like the sys.maxint causes problems (maybe problems between C++ and python type ranges?)

To reproduce it please run the attached code.
A new patch has been sent to the devel list.
It corrects some orthography errors and for python float we use C double (from 'f' to 'd').
