Did you make many snapshots? One after removing each plugin? Were you
able to track it down to which plugin(s) causes the issue?

Do you have any of those plugins available on OSX? And if yes: did you
compile or install them yourself (not using the ones shipped with Ardour)?

The most likely explanation is that there is more than one "libfftw3f"
installed on your system, Ardour2 ships one in its application bundle.
It seems that some plugin(s) expect(s) a different version.

There should be a warning printed on the "Console".  sth like
"ld: warning: duplicate dylib .. "

Snapshots are just a copy of the .ardour XML file. Usually a few 100 KB.
Audio-files are not duplicated (ardour is non-destructive).

It may affect the cleanup-feature:
   Session -> Cleanup -> cleanup unused sources

If a source is still used in one of the snapshots, it shouldn't get
cleaned up, but I'm uncertain if that is actually the case. Ardour3
currently does not check the snapshots, that may be a bug though.
