wnck-applet was segfaulting immediately when I logged in to GNOME. After
debugging, I discovered it was dying on a call into libstartup-
notification-1.so.0. For the hell of it, I reversed and then redid wnck-
applet's prelinking, and it worked fine.

So, yes, there is some kind of prelink problem going on.

Of course, I completely forgot to make a backup copy of the mangled
wnck-applet, so this doesn't help you much beyond a "me too!" (Although,
this is an AMD64 system, so that might be another data point).
