Cool - I've just installed it under Ubuntu using your ppa. You should
add dependency on gir1.2-gconf-2.0 package because it was not
installed by default on my system and your application ended with

Found this (see the first paragraph):

Actually I think it's a good idea to create their own map sources for
any serious application instead of relying on libchamplain's factory.
As you can see, tile sources can appear/disappear/change URL quite
quickly and people will have different versions of libchamplain
installed on their systems, each with a different (possibly outdated)
map sources so your application will work differently on each of the
systems. By creating your own map sources you get independent of a
particular libchamplain version and it is also much more flexible for
you when e.g. the URL of a map source changes.

I'd suggest that Emerillon should create their own map sources too.
