That worked for me. I reverted all GNOME components to the versions in that CTM snapshot, and then I upgraded them one at a time until the emacs problem appeared. This happened when I upgraded libglib2.0_0 from 2.30.2-1 to 2.32.2-1, so I downgraded it again. I also had to keep the following old versions: libgtk2.0_0-2.24.10-1 libgdk_pixbuf2.0_0-2.24.1-1 libpango1.0_0-1.29.4-2 When I tried to upgrade any of those, emacs would immediately exit with error 127. I guess they rely on features of the newer libglib. All of my other packages are up to date, and I can't detect any problems with emacs-X11-23.4-2 or emacs-X11-24.0.96-2. I'm trying to keep a fairly minimal set of packages installed on my XP system, so other people may find that they have additional packages that need to be downgraded to work around this problem. I hope someone (Yaakov?) will take a look at the glib changes between 2.30.2 and 2.32.2 and try to find the cause of this problem. I don't use gvim, so I don't know whether the same downgrades will help with the gvim problem.
