errors in color_convert routines

["David LaPointe" <david lapointenclick com>]

I'm new to the list.  So, if this is not the right list for me to post to 
for this type of question, please let me know.  Also, please forgive any 
ettiquette errors I might make.  I checked the FAQ and searched the list 
archives several different ways before asking this, and I don't see anything 
like this in either of those places.  I keep getting the following errors.
(dia.exe:2432): Gdk-WARNING **: gdk_property_delete: General case not 
implemented 

(dia.exe:2432): Gdk-WARNING **: window 0x00020582 unexpectedly destroyed
** (dia.exe:2432): WARNING **: color_convert failed. 

I'm running Microsoft's remote desktop client on a windows XP machine to 
connect to a windows 2000 server over terminal services to run dia ver. 
0.91. 

Does anyone know of any way to avoid this?  Something in the above list of 
errors has the result that everything in the diagrams displayed through dia 
show up as all black.  So, dia is completely useless in the face of these 
errors. 

Any help would be appreciated.
