stevygee1987 on "Saving Portfolio Settings gives Fatal Error if Permalinks are disabled"

Hello,
when I tried to update the plugin settings on a fresh Wordpress install, I got this error:

Fatal error: Unsupported operand types in (path)\wp-content\plugins\portfolio\portfolio.php on line 393

I found out that this only occurs if Wordpress Permalinks are disabled. It works fine otherwise. But others might not figure this out..
