what makes me wonder is, that I've had installed the naspro-bridges 
before updated lv2-core, jalv and jack, and they haven't harm the 
performance. After they do, without update the naspro-bridges itself.

Maybe a config switch were doubled plugs could be switched of generally, 
instead print warnings about, would be good?
As far I remember right, the problem with naspro seems to be that it not 
only add the ladspa plugs to the world, but scans again the existing lv2 
plugs and double them up, which leads to a huge amount of error messages 
in the terminal. My terminal cache was overflowed by the amount.
