I think at this point just throwing a general exception is probably best.
Havoc and I have in mind adding a GException API to GLib for doing
detailed error reports, so we may eventually have a standard way
of doing:
pixbuf = gdk_pixbuf_new_from_file_with_error ("myfile", &error);
if (!pixbuf)
g_print ("Could not load file, "%s\n", error->str);
But we don't have a standard way of doing this now.
You might want to file a wishlist bug report against gdk-pixbuf about
this in the GNOME bug tracker.

Owen
