Yes, that is incorrect. It is supposed to go to /graph?uri=...

Unfortunately the JavaScript Fresnel thing takes a *long*
time to render for changesets of moderate size (most of 

I think, especially for changesets because they should be
immutable, that this is a place for pre-rendering using
the python fresnel...

Some more recent work suggests a different approach,
however, that avoids reification (which is the part that
turns out to be processor intensive in the browser to
render), actually using graphs for cs:addition and
cs:removal. This has some things in common with EvoPat
from uni-leipzig. 

This would mean rejigging the changeset
implementation though, and in any event I actually 
dislike having it in the core handler part of ordf

bypass it, which is a good indication that it is in
the wrong place).
