Particular Activity View Creates WSOD When Filtering Out Node Comment Activity Messages

Hi,

Hope all is well with the Activity maintainers. I'm not sure whether or not to mark this a bug.

I have a View (attached) uses Activity Flag Access filters to include activity (nodes and users) of the things that users have flagged. The odd thing is that as soon as I add an Activity Type Filter to filter out, say, node comments the View will cause a WSOD for users who visit the view but do not have anything flagged. I thought this was odd enough to warrant the "support request" category. Still, most my views require displaying on certain types of activities but that are also of things that users have flagged so this is kind of a bummer for new users.

Thanks again for your efforts on this superb module,

Thomas
