It sounds like this might be a PHP 5.4 error specifically. I haven't seen this error myself, but my localhost and production sites are all still on PHP 5.3. On the other hand, I can't tell at a glance why this error would be happening. The 'exporter' key almost certainly should exist. Are you sure this is a clean installation of Webform that hasn't been modified?

I'm going to mark this postponed unless there's more information here I can use to debug this problem. At this point I don't know if Webform has been modified, it's a module conflict, or its a server configuration problem. If you can reproduce this problem on a clean installation of Webform, I'll take another look. But I don't have access to any IIS machines so I don't think I'd be much help if this is an environmental problem.
