Dashboard stuck on Please Wait

When I click generate on any items in the dashboard, it is getting stuck on “Please Wait…”

WP Retina 1.0, WP 3.5.1, PHP 5.2 or 5.4 (tried both).

Using debug messages I traced where the issue is coming from, seems to be in the media.php function wp_get_image_editor().

It seems like $editor is a corrupted variable (if that is such a thing in PHP?). After it is instantiated, if I try to wr2x_log(“$editor”); that line seems to hang as I can’t print anything directly after it either.

Example 1:

if ( empty ($editor) ) { *THIS WON'T EXECUTE }
*BUT A WR2X_LOG HERE WILL WORK*

Example 2:

if ( ! empty ($editor) ) {* THIS WON'T EXECUTE }
*AND A WR2X_LOG HERE WON'T WORK EITHER*

Here is a snippet of the wp_get_image_editor() function with my comments of where it hangs:

if ( $implementation ) {
**CAN PRINT DEBUG HERE**
		$editor = new $implementation( $path );
** CAN PRINT DEBUG HERE**
		$loaded = $editor->load();
** NEVER REACHES HERE TO PRINT DEBUG**
		if ( is_wp_error( $loaded ) )
			return $loaded;

		return $editor;
	}
