[PD] Tcl invalid command with [TuioClient] and Pd-extended 0.43.4

[Jack]

Hello,

I am working on a patch in which i use [TuioClient] with Pd-extended 0.43.4
When i open this patch, i get in the Pd console :

Invalid command name 'listening'
    while executing
"listening to TUIO messages on UDP port 3333"
    ("uplevel" body line 1)
    invoked from within
"uplevel #0 $cmds_from_pd"

Then, very often, there is no GUI and i can't use the patch.
How I can make this patch work (attached) all the time for an
installation (with TuioClient.pd_darwin from tuio.org) ?

My configuration :
MacMini with MacOSX.7.5
Pd-extended 0.43.4

Thanx.
++

Jack
