tiny-teeny fonts with KDE

["Adrian E. Feiguin" <afeiguin uci edu>]

Hi! I'm using the following code to calculate the size of some text:

  layout = 
pango_layout_new(gdk_pango_context_get_for_screen(gdk_screen_get_default())); 

// equivalent to gdk_pango_context_get();

  pango_layout_set_text(layout, text, -1);
  pango_layout_get_extents(layout, NULL, &rect);


This is because I don't have any widget available to use
gtk_widget_get_pango_context()

What happens is that if I use KDE, the text appears to be like 3 pixels 
wide!
Now, if you run gnome-font-properties, and restart the program, the 
fonts look fine.
I know some of these issues between gnome and KDE have been discussed 
elsewere, but my program doesn't use gnome, I'm using gtk and pango. 
What's the problem then? Is there a way to fix my code, without using a 
widget to get the context?

Thank you!
Saludos,
