I thought we had fixed that Ardour crash problem by removing the old

reports of these crashes?

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 that problem.

Anyway, I can't comment if the lsp-plugins offer the same
functionality/quality as the calf ones (as I have not used either of
them enough).

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 occasion.

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.
