Wohow, this is actually a bug introduced when we added Maps as parameter types. I added a test for it in the gremlin-plugin, and fixed it in server, https://github.com/neo4j/community/commit/ed42542e191de9966e1b5ada80bf8a6684bd6d1d
As snapshots get out, you should be able to run it normally in Neo4j Server 1.5-SNAPSHOT. Thanks for reporting it - it surfaces only when you do a GET on the Gremlin plugin URL!
