Is there any obvious legal problem with stating that (for example) "All material from Swedish Wikipedia may be freely reused, without further permission, with the exception of the Wikimedia trademarks and copyrighted logos, for which separate, specific permission for reuse must be sought"?
Yes, that is a longer sentence. But in my experience the kinds of people who agonize over copyright permissions are uniformly capable of parsing longer sentences.
Note that my suggestion handily dodges the need to instruct anyone about whether the Wikipedia image in the corner of the page is freely licensed for reuse. It also avoids the need to explain to someone what constitutes part of the user interface and what doesn't. It also doesn't require a non-law-trained user to parse issues of trademark versus copyright. So in fact it is a simpler, user-friendlier solution that seems consistent with David's statement of what Swedish Wikipedians want to be able to do.
