Confirming that truncating solves the problem. However, I've done this
just before the call to avahi_entry_group_add_service_strlst() in
publish_service(). This is probably wrong for many reasons.

Furthermore, I've done it using plain old strncpy() which knows nothing
about unicode...

Any chance you could point me where I should be doing these changes?

One last thing, it'd be nice if the avahi doxygen docs included the
63-character limit here [1]

Thanks for your help :)
