Dear Maintainer,
blender-2.66a-1 from experimental crashes here, this is the backtrace:

-----------------------------------------------------------------------
We have to fix fill_locales(), which still thinks the locale files are in
BLENDER_SYSTEM_DATAFILES.
I have an experimental patch which fixes the crash, I am going to post it as
a follow up mail, so I can use use the report number in it.
BTW, I think that blender should fail gracefully when it does not find
a directory or a file, it should not crash, maybe something like this can be
upstreamed:

This would avoid a possible crash even for the pristine code as fill_locales()
is called only when messagepath has been found.
But I have no time to properly test it and upstream it for now.
Thanks,
Antonio
