Patches for 79238, 80733, and 80731

[Dave Camp <dave ximian com>]

I've added patches to the following bugs:

  http://bugzilla.gnome.org/show_bug.cgi?id=79238

  http://bugzilla.gnome.org/show_bug.cgi?id=80733

  http://bugzilla.gnome.org/show_bug.cgi?id=80731

They mostly fix memory management problems.

Would someone mind taking a look at them please?

Thanks,
