172
173CV uses Pixbuf to load images. Pixbuf is not considered safe for this
174purpose, though (from the gtk-2.2 release notes):
175
176"While efforts have been made to make gdk-pixbuf robust against invalid
177images, using gdk-pixbuf to load untrusted data is not recommended, due to
178the likelyhood that there are additional problems where an invalid image
179could cause gdk-pixbuf to crash or worse."

183 Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names
184 incompatible with utf-8 fails.
