That's pretty bad because loading (dlopen'ing) parts with RTLD_GLOBAL is
asking for trouble. There is no way that we can guarantee that one part
doesn't by chance use the same name for some class/symbols as another part,
since parts may get developed independently of each other.
We are already running into trouble with the flash plugin colliding with
OpenGL (both define "DisplayList") and things like this aren't helping the
situation.
The alternative, banning RTTI from KDE, isn't very attractive either.
