bug#21203: 24.5; about-emacs makes emacs freeze on windows 8.1

[Pablo Mercader Alcántara]

When I call the "about-emacs" command (either through M-x or the menu)
emacs freezes, it stops accepting commands, it doesn't close and doesn't
redraw the content of its window. The only to stop it is using the "end
task" option in window's task manager.

This problem does not happen if I run emacs on text mode with the "-nw"
option.

This problem doesn't happen on emacs 24.3.1 text or windows mode.

I have the "inhibit-startup-screen" variable set to "t" in my .emacs
file, from previous uses in previous versions, but if I take it out
emacs freezes at start.
