TextEdit.app problems X11

[pedro alves]

Hi

I am have installed GNUstep and I am interested to install GNUstep  
applications to know how they work and later on learn how to program  
in Objective-c using GNUstep.

I have installed TextEdit.app.
The applications lunches but then the menus are draw but no text is  
found in the menus. Either all dialog boxes are empty. The Xterm  
terminal shows these kind of lines everytime a event call is made to  
the menu or dialog box.

"TextEdit[770] X-Windows error - RenderBadPicture (invalid Picture  
parameter)"
on display: :0.0
type: 0
serial number: 2688
request code: 153


What is wrong here and how to solve that?
I am running Xorg 7.2

Best

Pedro
