Another error which happens only in very specific circumstances.
In certain Workspaces, ia regular user performs the following sequence:
Documents > New > Upload a file > (the file is reckoned) > Add File
Fatal error: Call to undefined method
FileRepository_Backend_FileSystem::saveFileAttributes()
in /var/www/opengoo/library/filerepository/backend/FileRepository_Backend_FileSystem.class.php
on line 282
The permissions for that user and workspace are set correctly.
Admins can upload to that same workspace with no problem.
