178=head1 SECURITY CONSIDERATIONS
179
180CV uses Pixbuf to load images. Pixbuf is not considered safe for this
181purpose, though (from the gtk-2.2 release notes):
182
183"While efforts have been made to make gdk-pixbuf robust against invalid
184images, using gdk-pixbuf to load untrusted data is not recommended, due to
185the likelyhood that there are additional problems where an invalid image
186could cause gdk-pixbuf to crash or worse."

123=head1 BUGS/TODO 188=head1 BUGS/TODO
189
190 Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names
191 incompatible with utf-8 fails.
