Unfortunately, this is not the same cause as the other reporter, since
the attached files do load module-switch-on-connect and it is not
using system mode.

On this one you might get better luck asking upstream. I only note
that system mode is not as unsupported as it seems. I think upstream
needs to clear up a bit their messaging. So, it is not a problem to
use system mode.
