I think you've hit the same thing I did some time ago. If you read
http://www.selenic.com/mercurial/hg.1.html#largefiles
carefully you'll find

   The largefiles.minsize and largefiles.patterns config options will
   be ignored for any repositories not already
   containing a largefile. To add the first largefile to a
   repository, you must explicitly do so with
   the --large flag passed to the hg add command.

largefile is a feature with a big impact on the repo so developers of
Mercurial decided that you have to
explicitly turn repo into "largefiles" enabled one by invoking first
hg add --large manually. Later on
everything is just a breeze.
