Subject: [PATCH] Error in trace file for Dialog Options

When the New Account Hierarchy Assistant is used, the book options are
added to the assistant as a notebook page and so will not have a parent
widget to be used when restoring the window size so test for parent
before using gnc_restore_window_size
