Just a hunch (I have developed both LADSPA plugins and a host):
The problem may be due to the fact that some hosts have hard-wired
defaults for plugin locations. This makes them work for the default
case (plugins in /usr/lib/ladspa) even with no LADSPA_PATH set.
However, if it is set, the host may iterate over its hard-wired path
*and* the paths found in LADSPA_PATH, thus resulting in visiting
each plugin more than once. If this is indeed the cause, the fix is
to amend the host to drop duplicate paths from the merged list
of paths (from hard-wired paths and paths from LADSPA_PATH).
Or not use its hard-wired path at all if it finds LADSPA_PATH set.
