[Barry Warsaw]

Update of /cvs-repository/Zope3/lib/python/Zope/Publisher/Browser
In directory cvs.zope.org:/tmp/cvs-serv5524

Modified Files:
	BrowserLanguages.py 
Log Message:
getPreferredLanguages(): Don't crash if there's no
HTTP_ACCEPT_LANGUAGE in the request.  You don't get much useful
information (i.e. none of the explicit msgids are translated) but at
least you don't get a traceback.

FYI: When accessing the page via Python's urllib, there's no
HTTP_ACCEPT_LANGUAGE.
