[PD] Pd-extended bug

At RjDj we're interfacing Pd with Python using a wrapper I wrote, and one of
the developers had this bug report when he tried it with Pd-extended (not
realising that there is another type of Pd).

We're going to be using vanilla only, but I thought I should send a heads-up to
the list anyway incase someone else runs into this Pd-extended weirdness.

The bug report below doesn't happen on Pd-vanilla at all. See the attached
files to try and replicate it. Basically it seems like Pd-extended is crashing,
or not starting at all with Pd default command line args.

I have trouble being able to load pd from the command line with
the -open flag, pointing at the relevant scene. That is, pd seems to
load normally (though strangely showing only the console and not the
editor gui). There is the following command line output:
tk scaling is 0.999016715831
Pt_Start() called

When I try to send the patch a message from python (to a netreceive
object in pd), then python (using Chris' PdSend object) then I receive
the following error:
>>> pdSend.Send("hello")
error: uncaptured python exception, closing channel <Pd.PdSend
connected at 0x6f648> (<class 'socket.error'>:(32,
'Broken pipe') [/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/asynchat.py|initiate_send|219]

On the other hand, if I open PD and load the scene manually, then
everything works fine. Thoughts? -Martin
