Re: Gtk (HEAD) problem

Oki!

Here is the real debug report about:

GRuntime-CRITICAL **: file gvalue.c: line 48 (g_value_init): assertion
`G_VALUE_TYPE (value) == 0' failed
is happening on call to object_get_property() --> class->get_property
(gobject.c: 709)   

it seems like gtktexttag.c: get_color_arg() is calling g_value_init on an
already initiated GValue object
(This tmpvalue is initiated in g_object_get_property  gobject.c: 1214)

 Thats why this fails:

 GdkColor *col=NULL;
 GValue val={0,};
 g_value_init(&val,GTK_TYPE_GDK_COLOR); 
 g_object_get_property(G_OBJECT(tag),"foreground_gdk",&val);	

Greats

M.H.
