I've fixed the main file storage query to avoid the use of this view, apparently it's still used by this portlet.
I'll look into it.
Note, though, that due to our effort being pointed towards an OpenACS 4.6.2+dotLRN 1.0 release, any such fix will appear in the dotLRN 1.0 branch, not HEAD. We'll be merging the two in a couple of weeks but until then you're best off with those two branches.
