Way to reproduce:

  1. Open a graph file, undirected
  2. Create "Degree Range Filter" and enable filtering
  3. Play with range slide
    An exception is thrown sometimes, with higher probability is layout is active

Stack Trace:
java.lang.NullPointerException
at org.gephi.graph.dhns.edge.AbstractEdge.getUndirected(AbstractEdge.java:92)

I get the same symptoms in alpha 4 - here's the stack trace, which is different than from the original report
