227
228CV uses Pixbuf to load images. Pixbuf is not considered safe for this
229purpose, though (from the gtk-2.2 release notes):
230
231"While efforts have been made to make gdk-pixbuf robust against invalid
232images, using gdk-pixbuf to load untrusted data is not recommended, due to
233the likelyhood that there are additional problems where an invalid image
234could cause gdk-pixbuf to crash or worse."
148 235
149=head1 BUGS/TODO 236=head1 BUGS/TODO
237
238 Pixbuf doesn't honor G_BROKEN_FILENAMES, so accessing files with names
239 incompatible with utf-8 fails.
