eval issues - when newsession is not detected

[awb99]

When evaluing a new notebook, it all works fine.
Except the (ns macro) is not assigning line-plot to the "line-plot" variable.
Repo:

git clone https://github.com/pink-gorilla/trateg
cd trateg
lein notebook

In the notebook this is the problem:
(list-plot (concat (range 10) (reverse (range 10))))

error message:
Syntax error compiling at (REPL:1:1). Unable to resolve symbol: list-plot in this context

this works:
(pinkgorilla.ui.gorilla-plot.core/list-plot (concat (range 10) (reverse (range 10))))

this also makes a problem:

(ns parched-brook
(:require
[clojure.pprint :refer [print-table]]
))
(print-table [ {:a 1 :b 2} {:a 3 :b 4}])
