I´m running openSUSE 12.3 and do a data backup weekly using Deja-dup. Today´s backup validation failed. I noted when opening a file that an odd titled file showed up in the list of Recent Documents titled /tmp/nsmail.odt. When I attempt to open /tmp/nsmail.odt - a message file does not exist appears.

How do I get rid of this file that doesn´t exist?
