There is an option when dlopening whether you want to export that 
symbol to the other shared libs, to resolve whether -Bsymbollic-ly, or
-Bshared-ly, and the default was to -Bshared.

GNOME1/GTK1.2 experienced problems when GTK+ 1.2 applications were
linked with libpng3, some pixmap theme engines (which were dlopened)
were linked with libpng2, and they were dlopened with RTLD_GLOBAL.
