Original commit message from CVS: * gst/gstinterface.c: (gst_element_implements_interface): Don't crash if the element supports the interface queried, but does not implement GstImplementsInterface. Fixes #519584. * tests/check/Makefile.am: * tests/check/gst/.cvsignore: * tests/check/gst/gstinterface.c: Add unit test for the above.
