Since updating all ports after an update to FreeBSD-12, every time I invoke atril PDF reader, I see a gst-plugin-scanner process running at 100% CPU. I am guessing that the port is gstreamer1, as gstreamer also installed an identically named program. A TERM signal causes it to exit cleanly.
I have no significant details on this but would be happy to collect some with some advice on what to collect. (truss? ktrace? What options, if any.)
No longer an issue with current version of the ports.
