Bug 658732 had reported problems for OpenSUSE 42.3 (AFAIR).
It seems it was not "resolved upstream" since then.

Here are some correct errors:
Unable to insert multiple values for ... single valued property
`nie:contentCreated'
Unable to insert multiple values for ... single valued property `nie:copyright'
         nie:copyright
"-----------------------------------------------------------" ;
         nie:copyright "Copyright 1990-2015 Adobe Systems Incorporated." ;
         nie:copyright "All rights reserved." ;
         nie:copyright "" ;
         nie:copyright "Redistribution and use in source and binary forms, with
or" ;
         nie:copyright "without modification, are permitted provided that the"
;
(...)
So maybe copyright is either not single-valued, or the file from Adobe used it
wrongly.
The problem here is that it tried again and again, flooding the xsession error
log.

I have no idea what causes these.
