Comment (by ulfben):

 I don't want to come off as a complete tool, but it ''is'' confusing me.
 WP <2.7 (it seems) did not run this filter as frequently, and the various
 paths and URLs for uploads are stored in the database either way, right?

 Isn't it completely redundant to run wp_upload_dir() when "reading"?

 Thing is; there's no context to the filter call now. For the vast majority
 of runs in 2.7 my plugin can not return a useful path (no post is being
 worked with, so no dates, author name or other "path variables"
 available). I return the default one as a bailout, and WP seems to run on
 just fine still. So... is it really using these returns for anything?
 (remember - the default upload dir would be kind of useless on a system
 where everything is stored according to Custom Upload Dir-settings - so WP
 must be getting the correct paths from somewhere else).

 I fully embrace the possibility that I'm just misusing the filter or doing
 it wrong™ - but I hope the issue is relevant to more than just my little
 plugin. :)
