I applied the following patch:

diff --git a/lib/sup/message.rb b/lib/sup/message.rb
index 965c10e..9156c02 100644
--- a/lib/sup/message.rb

   def labels= l
     raise ArgumentError, "not a set" unless l.is_a?(Set)
     return if @labels == l
+    warn "labels=#{l.pretty_inspect}"
     @labels = l
     @dirty = true
   end

And get this in the logs:
