What version of dev-libs/glib are you using? If it is <2.10, please try emerging >=dev-libs/glib-2.10 and try again and let us know if that resolves the issue.
It compiles and works fine with >=dev-libs/glib-2.10, so i think this should be in dependencies of gst-plugins-base-0.10.4
You seemed to have upgraded to glib-2.10. Then when you downgraded the glib version, you did not rebuild the libraries which were built against the new glib, therefore, when you tried to build this, you recieved this error. You should either stay with glib-2.10, or build anything which depends on it.
