Is there any solution to this ?  Such wonderful plugins but, such an
hesitation in exploring them because it makes Ardour crash.  That it
crashes could maybe be OK is no data is lost, but there's a 'fear'
 that it may mess up a session altogether, and one in which much time
was invested.

If fftw is the root cause, maybe getting the latest from their
repository could provide some solution ?
