Indeed. There have never been labels, and now it's crashing, most likely
because of dereferencing the non-existing label array.

Do you mind to try this patch? Maybe it's enough. If Craig feels happy
to do some remote try&error, I can sort this out with him.

Right now, I'm simply assigning a stupid "1", "2" .. "64" channel
