[PD] Problem to access canvas properties with Pd 0.43.2test1

[Jack]

Hello,

When i try to get properties from a canvas, i get in the pd console :

(Tcl) UNHANDLED ERROR: wrong # args: should be "pdtk_iemgui_dialog
mytoplevel mainheader dim_header wdt min_wdt wdt_label hgt min_hgt
hgt_label rng_header min_rng min_rng_label max_rng max_rng_label
rng_sched lin0_log1 lilo0_label lilo1_label loadbang steady num_label
num snd rcv gui_name gn_dx gn_dy gn_f gn_fs bcol fcol lcol"
    while executing
"pdtk_iemgui_dialog .gfxstub804e43a8 |cnv|            
------selectable_dimensions(pix):------ 15 1 size: 0.0 0.0
empty             ------visible_recta..."
    ("uplevel" body line 1)
    invoked from within
"uplevel #0 $cmd_from_pd"

And the window properties doesn't open as expected.
Any help to solve this problem would be nice.
Configuration : Ubuntu 11.10, pd 0.43.2test1
