[Glade-users] Gtk Curve problem

[odiliscia unq edu ar (Oscar Pablo Di Liscia)]

Hi all:

I am using the gtk_gamma_curve Widget and each time I run 
my program I get the following error:

Glib-Error: Could not allocate -20 bytes

I get also the same error that I get using the gtk_curve 
(instead of the gamma) and attempting to change the curve 
type (using the gtk_curve_change_type) to GTK_CURVE_LINEAR.

I know that gtk_curve and gtk_gamma_curve are not Widgets 
widely used, but anyway may be most handy for my purpouses. 
Any help on this will be most appreciated.
Most cordially

Oscar
