Bad encoding of file download URLs
Links on event detail pages (in the log messages) (probably for superevents, too) with special characters in them like '#' don't work properly. They are OK on the event file list page (probably because the url template tag encodes them properly).
We can use probably use encodeURLComponent() in Javascript to fix the issue in the log messages. We should check on the file lists for superevents too. And we will have to patch the client to encode the URL properly in the files() method.
