#3734: Location wizard on python 3 seems to be broken
--------------------+-------------------------

 Priority:  normal  |  Milestone:

--------------------+-------------------------
 I compiled grass gis from source using python 3 and the location wizard
 seems to be broken. More specifically clicking on the "New" location
 button shows a window with the text:

     Unable to read list: dict_items object has no attribute 'sort'

 This is rather typical in python2 code which runs with the python3
 interpreter. I checked the source code of
 grass/gui/wxpython/location_wizard/wizard.py and fixed that but then the
 New button does nothing.

 Any suggestions WRT how I could see the full traceback?

 BTW, from now on, is python code supposed to be both Python 2 and 3
 compatible? Or Python 3 only?
