Comment:
According to the gpsd manpage: it should be automatically setting its own group to dialout when you provide it a device node (eg /dev/ttyACM0) that has the group dialout.  Something in the default application behavior is being overridden.

N.B. the manpage makes no mention of the group 'gpsd'.  That might be unique to the packaging here.
