I've installed ensime according to the README.md file, however, I get errors in the inferior-ensime-server buffer with the following:

Also none of the type identification works for me, I get 'NA' if I get anything at all. C-c t causes emacs to lock up.

I'm running:

Ubuntu 10.04 (64bit version)
emacs 23.1.50.1
ensime from git (as of 3 May 2010)
scala is version 2.8.0.RC1
java is 1.6.0_20 (from sun)
here is a copy of the log: http://dl.dropbox.com/u/5309017/ensime.log

Thanks!
