Adam thanks for working on this.  Yes this is a simple fix, and thanks for the patch.

When building the package I get a pydist warning concerning python-django-nose.  This can be corrected by adding python-django-nose to Build-Depends.

When runing lintian -iIE horizon*changes I get:

N:    should be possible to substitute the package name and synopsis into this
N:    formula:
N:    
N:    The package name provides {a,an,the,some} synopsis.

N:    This package contains a *.ttf, *.otf, or *.pfb file, file extensions

N:    appear to be a dedicated font package. Dedicated font package names
N:    should begin with fonts-. (Type 1 fonts are also allowed in packages
N:    starting with xfonts-.) If the font is already packaged, you should
N:    depend on that package instead. Otherwise, normally the font should be
N:    packaged separately, since fonts are usually useful outside of the
N:    package that embeds them.

N: 
N:    The synopsis (first line in the package "Description:" field, the short
N:    description) ends with a full stop "." character. This is not necessary,
N:    as the synopsis doesn't need to be a full sentence. It is recommended
N:    that a descriptive phrase is used instead.
N:    
N:    Note also that the synopsis is not part of the rest of the

N:    description should provide a user with enough information to decide
N:    whether they want to install this package, what it contains, and how it

It would be nice if you corrected these lintian warning or override them.

What concerns me the most is that debian/copyright does not conform to the DEP5 spec and the embedded font and java script libs.

Have a nice day
