 Warnings for init file are not visible after loading the desktop
Date: Fri, 04 Jul 2014 02:22:19 +0300

When an error occurs while loading the init file, the
*Warnings* buffer is displayed but hidden immediately
when the desktop restores the previous window configuration
by running `desktop-read' from `after-init-hook'.

A possible solution is to postpone displaying the
*Warnings* buffer to the end of `after-init-hook':

Fixed in the emacs-24 branch since it's a regression.
