anyhow, as i don't have any machine to reproduce your problem i have 
checked in some changes to the pd-extended 0.40 branch that might fix 
the issue.
the main difference now is that Pd does not try to automatically start a 
jackd by itself, so you have to do this manually (which is compatible to 
the usage instructions before my original patch)

tell us whether it helped.
and if not, also please give a complete step-by-step description on how 
to reproduce it (preferrably without the need of special hardware)


PS: if you use the sf-tracker for this, please create a bugreport 
instead of adding to the "patches"
