g_new() is used in only 3 places. Switching them to g_new0() will do no harm, reduces confusion, and helps me sleep better at night knowing that all allocated memory is initialized to 0 :-) (Yes, I *know* that in all three cases the associated memory is immediately assigned some other value. Today.) Signed-off-by: Laine Stump <laine@redhat.com> Reviewed-by: Ján Tomko <jtomko@redhat.com>
