Hi,

I've just tried to install BloodHound in the 'de' locale and it wouldn't work 
with this error trace:
   Traceback (most recent call last):
     File "bloodhound_setup.py", line 485, in <module>
       bsetup.setup()
     File "bloodhound_setup.py", line 195, in setup
       translation.activate(locale)
     File 
"/Users/spielmann/prog/bloodhound/bloodhound/trac/trac/util/translation.py", 
line 326, in activate
       translations.activate(locale, env_path)
     File 
"/Users/spielmann/prog/bloodhound/bloodhound/trac/trac/util/translation.py", 
line 153, in activate
       t.add(Translations.load(locale_dir, locale or 'en_US',
   AttributeError: 'NullTranslations' object has no attribute 'add'

Changing the rather unusual test in line 149 of /trac/trac/util/translation.py 
to a regular isinstance test seems to fix the issue. A patch is attached.

Cheers,
Johannes


Thanks for that Johannes. Though this patch is effectively for trac, I suspect that a lot of our users will experience problems so I am very happy for you to have brought it up for us.

In fact, this problem also seems to have turned up on our demo servers which, up until recently, were building correctly. Seems like we probably need to look into why this should suddenly be the case.

Cheers,
    Gary
