First, it looks like you may have an old install of Zyn in ~/.lv2/ if that's the case you should ensure you only have one version of Zyn installed. Second, I know ardour has some documentation on how to launch ardour with gdb. If you do so, then you should be able to see the source of the crash, though I would recommend doing so only after resolving the first issue.
