When viewing revisions that create branches, the diff display should ideally be hidden, but displays error messages instead.
In r49081, a rev resulting from svn mkdir, there is no diff to show, resulting in the "Failed to load diff." error message.
In r49082, a rev resulting from svn copy, the diff would probably be huge, resulting in the "Diff load failed. :(" error message. This one took considerably longer to appear than the previous one.
Of course this isn't a huge issue, but since failures aren't cached, it's wasting resources.
