Redmine

Hi, i've recently upgraded Redmine to version 1.3.1 stable. It seems as if everything works fine, except the svn repository browser. I can access the svn using the url http://mydomain/svn, but in redmine i get the message "entry and or revision doesn't exist in the repository". I checked the error log and this is what it says:

svn: Unable to open an ra_local session to URL
svn: Unable to open repository 'file:///var/svn-repos/sms-gateway'
svn: Can't open file '/var/svn-repos/sms-gateway/format': Permission denied
svn: Unable to open an ra_local session to URL

I found some forum entries describing the same problem, but their solutions didn't work for me. Is there anything I maybe forgot after the upgrade?
