246=head1 SECURITY CONSIDERATIONS
247
248CV uses Pixbuf to load images. Pixbuf is not considered safe for this
249purpose, though (from the gtk-2.2 release notes):
250
251"While efforts have been made to make gdk-pixbuf robust against invalid
252images, using gdk-pixbuf to load untrusted data is not recommended, due to
253the likelyhood that there are additional problems where an invalid image
254could cause gdk-pixbuf to crash or worse."
168 255
169=head1 BUGS/TODO 256=head1 BUGS/TODO
257
258 Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names
259 incompatible with utf-8 fails.
