While I was under the impression that g_ptr_array_*() would handle a
NULL ptr array, I see no harm in the patch itself, especially
considering its in a test. I applied the patch to 3.5/master, thanks!

For the record, I never saw the crash, so perhaps it happens only with
specific glib settings... Do you have any G_DEBUG or similar environment
variables set? If not, can you tell me how your glib was compiled, or
which distro this crash happens on?
