PHP 5.4 warning when updating plugins

Reported by: knutsp Owned by: ryan
Priority: normal Milestone: 3.5
Component: Warnings/Notices Version: 3.4.1
Severity: minor Keywords: has-patch
Cc: knut@…

Description

When updating plugins from either /wp-admin/network/update-core.php (Multisite) or from /wp-admin/update-core.php (Single site) I get this error logged (many times), using PHP 5.4:

PHP Warning:  Creating default object from empty value in /mysite/wp-admin/includes/update.php on line 90

update-core.php:89 reads

	if ( ! isset( $cur->current ) )
		$cur->current = '';

I'm not sure what is the best approach to avoid this. Both the bad (?)

		@$cur->current = '';

and the better (?)

	if ( ! is_object( $cur ) )
		$cur = new stdClass;
	if ( ! isset( $cur->current ) )
		$cur->current = '';

will avoid the warning, and seems to work.
