[evolution-patches] Prevent mailer crash on exit

[Ettore Perazzoli <ettore ximian com>]

I just found this while using Alleyoop.  If you quit Evolution while the
password dialog is already up, the dialog's widget gets destroyed but
the corresponding pointer doesnt get cleared, which causes the code to
access garbage memory.

+	* mail-session.c (request_password): Make sure password_dialog is
+	NULLified when the dialog is destroyed in any case, using
+	g_object_add_weak_pointer().  Prevents a crash that could happen
+	if the shell would quit with the password dialog still up.
