Is that only when you have --debug enabled?
If so, it's probably your web browser asking for the favicon and the
server responding with a silly "mr yuck" face.

It would be pretty trivial to hack the source to do that (I could help there).
I'd like to add this functionality in general, but I haven't worked out the packaging issues. Specifically, I'd like to take the favicon and the generated HTML at the root out and put them into the filesystem somewhere. Issues:
  where's that somewhere and how does the executable find it? (it should have a convenient zero-config behavior)
  what's the interaction between named graphs and the filesystem? GET and PUT of some named graph has nice behaviors now; should they be shadowed in the filesystem?

TimBL's leaning on me for the filesystem shadow. I have to write some serializers to make it work.
