Confluence logs: "Web Metadata cannot be retrieved more than once in a request"

Question

I'm seeing the following warning a lot in my Confluence log files:

2015-04-21T10:54:18.511 WARN [ajp-bio-8009-exec-31] [com.atlassian.confluence.plugin.webresource.DefaultConfluenceWebResourceManager] getMetadata Web Metadata cannot be retrieved more than once in a request
 -- url: *removed* | userName: anonymous | referer: *removed*

Any ideas what could be causing this and how I could get rid of it?

@Hans-Jürgen Hartl: Nope, I don't have an answer yet. To be honest, I haven't really spent time investigating this since the problem doesn't seem to affect Confluence usage. Still, it's annoying to see logs flooded with these messages.

guess it has something to do with requiring resources and setting metadata multiply

Did you get an answer on that somewhere else? Having the same problem...
