gramps/gramps2/src/PeopleModel.py
Don Allingham 335580cc90 * src/PeopleModel.py: provide a work around for the python 2.3 bug unicode 
sorting problem with locale.strcoll. For a nul termination during sorting,
strip it off after sorting. Only used for python2.3, since this bug was
fixed in python 2.4.
