GLAME high pass filter freezes ardour

On a just fresh installed kubuntu computer (ardour2.0 from ubuntu studio sources) the GLAME high pass ladspa plugin freezes the system (when I use e.g. 10 such filters) when playback is stopped.

Maybe thats a denormal problem ?

Is this a known bug? Otherwise I can give more information if needed !

fixed in swh-plugins version 0.4.15 (amongst many other denormal fixes)

strangely they are not yet shipped with ubuntu-studio …
