Do you plan to apply this to the 2.8 branch too?

Ben and I have gone through all the engines in gtk-engines making sure 
they pass the test. Expect a new release of gtk-engines very soon 
(before GNOME 2.14).

However, I'm not entirely clear whether this will solve the problem with 
the library trying to call a function within the application. Most 
internal functions in gtk-engines (that aren't static) are now prefixed, 
so this reduces the chances of the problem occurring. However, according 
to bug 326249, engines should be loaded with RTLD_NOW to be sure this 
doesn't happen.
