Unless I'm looking at the wrong revision in svn, the call doesn't  
appear to be present in 2.8.20. I suppose I could have worded the  
report a bit better; I upgraded libgtk2 when debian unstable switched  
from 2.8 to 2.10 and found that I could no longer display gtk apps to  
my SGI.

That's entirely possible.
