slimv - error connecting to clojure swank server

Tried to get slimv running today, but ran into an issue. These are the steps I went through:

• Installed clojure 1.3.0: brew update && brew install clojure
• Setup swank-clojure: lein plugin install swank-clojure 1.3.3
• Cloned slimv: hg clone ssh://hg@bitbucket.org/kovisoft/slimv
• Restarted macvim, opened existing clojure project, verified the slimv menu shows up
• Started a swank server with lein swank

• Tried to connect to it from macvim. This error showed up in the terminal that was running swank:

  exception in read loop

Any ideas? I also tried using swank-clojure 1.2.1 and clojure 1.2.

There seems to be a python related problem in macvim (see this thread for example). Some macvim snapshots work, some don't. A user tried to compile a snapshot that was segfaulting with python support linked against 2.6 instead of 2.7, and it solved the crashes. So it must be a problem with the python 2.7 binding, try to change it to 2.6 if you can.

You can verify the python version from within vim via this command:

:python import sys
:python print sys.version_info

However, I'm not sure you have the same problem, as you did not mention any segfaults, but maybe the difference is that you use clojure instead of clisp.
