	Hi,
that looks pretty good. Thanks for the inclusion of the libical-glib
in the upstream version.

I re-run static analysers on the git master at commit b2293fa7f and
uploaded the results here:
https://people.gnome.org/~mcrha/libical/libical-master-commit-b2293fa7f.html

I turned on some more options, thus it's more picky, but not everything
might be considered an issue, some are pure hints.
	Thanks again and bye,
	Milan
