import into repository option disabled in Netbeans on Ubuntu

I have created SVN repository on Ubuntu 10.04. I manually imported a project to repository and then checkout it in Netbeans and it works fine. Now I have created a new project in Netbeans and I would like to import it into repository using Netbeans Import Into Repository feature (rather than manually) but it is grey out (can't c开发者_开发技巧lick on it). Not sure why is that like this.

Make sure you do not have any .svn folders within the (new) project. Also, close NetBeans, delete %NetBeans_User_Dir%\var\cache and try again after starting NetBeans.

Edit: Looks like this is a randomly occurring bug. Can you try what he/she suggests?
