Error messages for colorselection dialogbox

[Allaud Emmanuel <emmanuel allaud skynet be>]

Hi,
I have tested testgtk, it worked very good. There was just a problem with
color selection : when you close it, gtk sends a lot of 
Gtk-CRITICAL **: file gtkstyle.c: line 575 (gtk_style_unref): assertion
`style->ref_count > 0' failed.
Is there anyone who faced that too ?
I hope it isn't something yet known :)
