org.jetbrains.idea.svn.SvnVcs cannot be cast to org.jetbrains.idea.svn.SvnVcs

Hello,

I'm developing a plugin for IC 11 EAP that uses the IDEA SVN.
When I'm trying to use anything about the svn plugin I always get "org.jetbrains.idea.svn.SvnVcs cannot be cast to org.jetbrains.idea.svn.SvnVcs". For example:

final SVNInfo info = SvnVcs.getInstance(project).getInfo(data);

java.lang.ClassCastException: org.jetbrains.idea.svn.SvnVcs cannot be cast to org.jetbrains.idea.svn.SvnVcs
at org.jetbrains.idea.svn.SvnVcs.getInstance(SvnVcs.java:679)

Any idea? Is it because I'm using EAP versions?
Any suggestions?
Thanks
