AssertionError: Assert failed: (vector? (:dependencies project []))

[Deleted user]

I'm using the latest lein from master, ie. this was last commit: technomancy/leiningen@fbc1804

Then compiled latest catnip from master using this lein, ie. last catnip commit was: 64db9c6

Then, lein new myproj somewhere.

c:\1>cd myproj

c:\1\myproj>lein edit
