Unable to change permissions on a space.

Every time I try to add a user or group to a space using the Invite Users Wizard, it takes my information and then thinks for a very long time before timing out.

The error message is:
"Please correct the errors below then click Finish.

    * A system error happened during the operation: JDBC exception on Hibernate data access; nested exception is org.hibernate.exception.GenericJDBCException: could not insert: [org.alfresco.repo.domain.hibernate.DbPermissionImpl]"

I'm running Alfresco on a Tomcat server behind Apache, so that I can enforce SSL connections, using mod_jk.  However, nothing else causes any problems.

Any suggestions?

Addendum:  This happens when I create rules on content, as well.

HOWEVER:  It happens only on *new* spaces I create.  If I change permissions on Company Home, or add a content rule to Company Home, it works correctly as far as I can tell.
