Answer 1

I think you have to first check in your error log number "1130478184" where you exactly know what is the issue. I think from your given link which you refer your issue must be occured from theme.xml file's <preview_image>media/preview.jpg</preview_image> line. You have to try with comment following code in theme.xml file:-

<!--media>
     <preview_image>media/preview.jpg</preview_image>
</media-->
