As one more data point, if I comment the two return statements (the
XmlReader and the Json.decode) the call to the subprocess gets parsed and
called. I'm getting a weird exception, though:

I've checked and the letters "dvl" don't appear anywhere in my source. OTOH,
printing out the tree after parsing looks fine...
Also, I've created a subclass of RuoteAMQP::Reader that overrides the
decode_workitem method. It finds the process to load based on the message
content and then returns a Hash of the form { 'fields' => {a hash of
fields}, 'definition' => '/the/full/path/to/the/pdef.rb' }. In that case, if
I leave the XmlReader and Json.decode lines in there I get the following:
20110317-bihawamunu TypeError

Again, by commenting the 2 returns in Ruote::Reader.read (the XmlReader and
Json.decode) I get the same "unknown regexp options - "dvl" " exception but
the workflow is read correctly.
Thanks!
