Timezone for "Africa/Kigali" defaults to pre-1903 definition

This is a bit of an odd one, and I think I learned a bit about some crazy timezones in the past.

In pytz 2014.7, a request for the timezone for "Africa/Kigali" correctly returned CAT:

>>> import pytz
>>> pytz.__version__
'2014.7'
>>> pytz.timezone("Africa/Kigali")
<DstTzInfo 'Africa/Kigali' LMT+2:00:00 STD>

But in pytz 2014.9, instead we get LMT

>>> import pytz
>>> pytz.__version__
'2014.9'
>>> pytz.timezone("Africa/Kigali")
<DstTzInfo 'Africa/Kigali' LMT+2:10:00 STD>

This seems wrong, as LMT was only in use up to 1903 and it *feels* more correct to return a timezone for the present as the default case unless someone asks otherwise.

We noticed this when some unit tests broke and it took a bit of tracking down that pytz changed its behavior.

Is there a reason for this and is the current behavior the "correct" way? I suppose we could work around it in various ways if so, but thought I'd report this if not.
