We ran into problems with some.po files whose translations modified
variables in strings (making them unparsable).
The solution we came up with serves two functions:

   1. it is compatible with setup.py genpot (since we use _
   2. protects against unparsable translations / prevents crashes

If unable to parse the string, we default back to the original language (not
optimal, but better than crashing).

Here's some code:

from gettext import gettext as gt

	#defensive method against variables not translated correctly
	def _(s):
		#todo: permanent variable
		istrsTest = {}
		for i in range (0,4):
			istrsTest[str(i)] = str(i)


		i = s
		try:
			#test translating the string with many replacements
			i = gt(s)
			test = i % istrsTest
		except:
			#if it doesn't work, revert
			i = s

		return i


Use the returned value from this method when you need internationalized
strings in your app.
