We just upgraded from 2.1.16 to 2.2.13. One user is experiencing
problems when using the shared namespace. Specifically it happens when
opening/reading a message and when deleting messages. These functions
work for other users. So far, this appears to be only affecting one user.
The shared folder is a local ext4 file system and utilizes acls
