Looks harmless to me (and downloads fine here). Wait - when I search for it I find it, but there is definitely something wrong here. There are several results for the hash (black dot in front of it), so when you doubleclick it it expands the tree instead of adding the download.
But the tree expansion goes wrong. In SVN debug I get an assertion, 2.2.6 expands it (but wrong). I'll investigate.
Please try "right-click/download" instead of doubleclicking. Does that work?
