[evolution-patches] Patch to fix crash when expanding "On this Computer" in mailer

[Rodney Dawes <dobey ximian com>]

This patch fixes the much disputed crashing in the treeview without
patching gtk+, as we are doing the wrong thing in camel also, when
loading local folders that don't actually have children, but we force
the CAMEL_FOLDER_CHILDREN flag even when the sub-directory is empty,
or only contains files that we want to ignore (those that being with a
period).

This also fixes the issues where folders would have an expander that
would do nothing when clicked (which is essentially what seems to be
causing the crash).
