That fixed the crash every time problem :)
Calf plugins are built using system gui libs and as such have a shared
namespace with other gui libs which sometimes confict and some times
don't... when they do they create odd crashes that may not seem connected
to the plugin. The devs at calf are switching the gui to their own
(static build) gui (all plugins should be static built) which should fix

I sure hope not! Quality != Calf. The general comment by professional
audio engineers is that the DSP in Calf is some of the lowest quality
available. The controls do not do what they are supposed to do, The EQ
causes phasing problems, the controls can not be automated because they
are not dezippered. The reverb may return a signal that is +1000 dB on
The only people I know who use Calf a lot, do so because they like the
sound and are using that artistically. (Unfa for example)
However, for straight mixdown use they are the poorest choice available.
Ardour already comes with the a-series plugins that includes much of the
same functionality. LSP is quite good, x42 is very good, eq10q is a good
set, zam is quite good (these are the a-plugins with extras). The
dragonfly reverb is very good and being actively developed with the help
of clasical recording engineers (who are quite picky I might add).
Every time I see someone suggesting calf plugins to a new user, I cringe.
