Some investigation has revealed that the GTK people have found this error on 
the mailing list; for those interested, subscribe to the mailing list (mail a 
message to gtk-list-request@redhat.com with subject 'subscribe') and get the 
following files (using the archive get command):
latest/2175
latest/2177
latest/2183
latest/2179
latest/2195

For those feeling lazy, the following patch was posted to the list and 
apparently works:

Message latest/2195 has a longer patch which I won't duplicate here; this 
patch dates from 5/1/99 so it may be in the distribution already.

FWIW, this problem also seems to occur under IRIX.  It seems to be caused by 
the program attempting to display 24-bit pixmaps on an 8-bit display; however, 
it works fine for me on a CG6 display which can only display 8 bit colour.  
Something seems to pick up that the frame buffer is capable of displaying 
24-bit colour and tries to use it. *shrug*
