Unfinished entity reference warning in GtkTextView

[Gaurav Jain <gaurav adobe com>]

Hi,
 
I'm using a GtkTextView and in that whenever, in my app, I enter the
character "&" inside the text edit, the following warning is thrown:
 
** (myapp:28271): WARNING **: pango-layout.c:830: Error on line 1:
Unfinished entity reference
 
I get similar warning when I type "<", something like:
** (myapp:28271): WARNING **: pango-layout.c:830: Error on line 1 char
118: '<' is not a valid character following a '<' character; it may not
begin an element name
 
It seems that Pango thinks I'm trying to write markup text, while I'm
actually not.  Is there some way to get rid of this warning?
 
Thanks,
