Jetpack 3.2.1 nvgstcamerasrc (libgstnvcamera) hangs

The version of installed by Jetpack 3.2.1 for the TX1 hangs when starting nvgstcamerasrc.

gst-launch-1.0 nvcamerasrc ! fakesink dump=true

Running /usr/sbin/nvcamera-daemon has no output and the camera isn’t invoked.

Has anyone else noticed the same problem? I have seen it on both of our TX1 devkits.

Completely reflashing the board and reinstalling seems to have fixed it. Something must have been out of date.
