I have pinned down the exact moment in gdb when brake-right is set to 1.0
(without a cause, so to speak), but I feel I don't have enough knowledge
about how FG is designed to come further.
gdb backtrace below. This is after initialisation is done, FG is up and
running and the fire button (apply all brakes) is pressed and held. Just
before this br stop, there was another one with the correct value (from the
nasal setprop to 0.3, which I used for testing instead of interpolate() in
the js config file). I have not a clue where this spurious "1.000000" comes
from, nor why it only affects the right wheel brake. It seems like more
than one function has been bound to the button in question, or some list
handler is running amok.
