Opening JRuby's pom.xml fails

Hi,

I checked out JRuby's trunk today:

$ svn info
Path: .
URL: http://svn.codehaus.org/jruby/trunk/jruby
Repository Root: http://svn.codehaus.org/jruby
Repository UUID: 961051c9-f516-0410-bf72-c9f7e237a7b7
Revision: 5666

and tried 'Open Project' on pom.xml. IDEA complained:

For artifact {org.apache.maven.wagon:wagon-webdav:null:jar}: The version cannot be empty.

Strange thing, I built the project using Maven 2.07 just minutes ago w/o problems.

I'm running IDEA #7648 on OS X.
