-This patch works around a segmentation fault in 'Magick++/tests/color' when
-running 'Magick++/tests/tests.tap'.  Here we get an exception early on, which
-is supposedly harmless:
-
-  Caught exception: color: UnableToOpenConfigureFile `colors.xml' @ warning/configure.c/GetConfigureOptions/706
-
-However, when the stack unwinders run, 'UnregisterDOTImage' gets called even
-though 'RegisterDOTImage' hadn't been called yet; thus, 'graphic_context' in
-coders/dot.c is NULL, leading to the segfault.
