22270	update-core.php is empty after choosing core upgrade to 3.4.2	szotsaki		"On a WP install 3.4.1 I noticed there is an option to upgrade to 3.4.2.

I invoked the URL ""/wp-admin/update-core.php?action=do-core-upgrade"" with the blue button and only an empty, blank page appeared.

POST variables:
{{{
_wp_http_referer	...
_wpnonce	...
locale	hu_HU
upgrade	Frissítés most!
version	3.4.2
}}}


I debugged that in /wp-admin/includes/update.php:73 in the ""find_core_update()"" function, on the first line, the variable $from_api gets a bool(false) value and that's why the whole function immediately returns with false.
