I'm having the same problem:

> git-annex: c:\Users\TV\annex\.git\annex\objects\566\a33\URL--quvi&chttps&c%%www.youtube.com%watch,63v,61XS-kKX9wQk0,38index,615,38list,61PLQ-uHSnFig5NCQkhJfkn8ogXFwzrP4SIf\: openTempFile: does not exist (No such file or directory)    
> failed    
> git-annex: init: 1 failed    

In my case the filename is slightly shorter, 154 characters, for Aaron the offending filename was 162 characters.

I think the full filename that git annex is trying to write is 270 characters:
