+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.
