zynJackU: 6-0tstudio2 (thats from the "TangoStudio" repo)

Apologies, with lv2host I meant Lv2Rack, which i think is based on zynJackU, (or partially uses its code), as it mentions zynJackU in the backtrace. Probably to do with the manifest file, the backtrace is pretty much identical.

Upon testing with lv2_jack_host the plugin works gets instantiated ok, and is running in the jack graph. Haven't played with it yet though...

Cheers, -Harry
