LV2 help !!

Hello all,

I get the following errors when running an experimental LV2 plugin
in jalv:

lilv_plugin_get_unique_internal(): error: No value found for (http://lv2plug.in/ns/lv2core#InputPort http://lv2plug.in/ns/lv2core#symbol ...) property
lilv_plugin_load_ports_if_necessary(): error: Plugin <http://kokkinizita.linuxaudio.org/linuxaudio/lv2/test7> port symbol "" is invalid
lilv_plugin_get_unique_internal(): error: No value found for (http://lv2plug.in/ns/lv2core#InputPort http://lv2plug.in/ns/lv2core#symbol ...) property
lilv_plugin_load_ports_if_necessary(): error: Plugin <http://kokkinizita.linuxaudio.org/linuxaudio/lv2/test7> port symbol "" is invalid


This apperently refers to these two ports:

...
	], [
		a atom:AtomPort, lv2:InputPort ;
		atom:bufferType atom:Sequence ;
		atom:supports midi:MidiEvent ;
		lv2:index 2 ;
	 	lv2:symbol "midi_in" ;
	 	lv2:name "MIDI In" ;
	 	lv2:portProperty lv2:isSideChain ;
	] , [
	 	a lv2:ControlPort, lv2:InputPort ;
	 	lv2:index 3 ;
	 	lv2:symbol "midi_ch" ;
	 	lv2:name "Midi chan" ;
   	        lv2:default 0 ;
	 	lv2:minimum 0 ;
	 	lv2:maximum 16 ;
	 	lv2:portProperty lv2:integer ;
        ], [
...

If I replace those by AudioPorts all seems to be OK.

Clearly the symbols are not "", so what's the problem ?
