When logging out of Mate, I am confronted with a window stating at.spi.registryd.desktop not responding. After clicking the logout anyway twice and waiting for about a minute or two the logout is carried out and the main screen states that the mate-session shutdown was not found. Thus, I searched in the mate tools window and opened the system monitor thread and found the at-spi2-registryd file running. I killed the file and carried out a typical logout of the mate-session and found that the logout to be immediate such as before I reinstalled BSD 12.1 and rebuilt the desktop. I use packages mainly to build the desktop ports and before I install mate I install gnome3. So, here is my question, how do I remove an embedded file such as at-spi2-registryd in the /usr/local/libexec directory? Even as root I am not able to remove it (permission issue). Any thoughts will be appreciated.
