Anyway, to render such images properly in ikiwiki I had to remove the colons. An easy fix is to remove ‘:’ from `wiki_file_chars`, but this can break existing installations. A better solution would be to make `IkiWiki::Plugin::img` croak on such image filenames (which anyway are currently not rendered, but `Image::Magick`'s error message is quite cryptic).
