> plumb start /usr/matt/bin/web_plumber -w tcp!192.168.1.101!8005 ''$0''

i don't understand why this works.
i've been testing with

type	is	text
data	matches	'=.*'
plumb	to	echo
plumb	start	window webbrowser ''''$0''''

and i need four quotes.

i also can't reproduce your print format
problem, but here's how to debug it:
plumb

	http://whatever/%s%s%s%s%s%s%s%s%s%s/

and then do

	ps |grep Broken
