[opencms-dev] publishing project with new owner

[enol]

Hi List...
I create a new user group and put in a new user.
Then I set all folders and pages of my project to this user like owner
and set the rights rwvrwv---- (for permit the reading to these pages/folders
only to this new user).
When I publish my project I get some errors like this:

Exception com.opencms.core.CmsException: 8 Unknown User Group. Detailed
