The XkbSelectEventDetails call was added much earlier than the 2.10
series. I think you're talking about the following change:
http://svn.gnome.org/viewcvs/gtk%2B/trunk/gdk/x11/gdkdisplay-x11.c?view=diff&r1=15911&r2=15912

In all cases, this looks like a bug in Xsgi rather than one in GTK+, but
I'm CCing Matthias, who committed this change. Matthias, do you remember
why you did this change? I can't find anything relevant in the
ChangeLog.

Thanks,
