## Remarking these two lines because they are causing a segfault:
##  ../src/common/stdpbase.cpp(62): assert "traits" failed in Get(): 
##  create wxApp before calling this
##  Segmentation fault (core dumped)
##
##  I do not know how to test or fix this, hence simply removing it.
##  AFAICT, stock buttons will be in the system language.
##
## Setup wxPython to access translations : enables the stock buttons.
##langid = wx.LANGUAGE_DEFAULT # Picks this up from $LANG
##mylocale = wx.Locale( langid )

## langcode = locale.getlocale()[0] # I must not use getlocale...
## This is suggested by Martin:
loc = locale.setlocale(locale.LC_CTYPE) # use *one* of the categories (not LC_ALL)
## returns something like 'en_ZA.UTF-8'
if loc is None or len(loc) < 2:
	langcode = 'en'
else:
	langcode = loc[:2].lower()# This is going to cause grief in the future...
