Certain characters are not allowed in store item[0] names.  This 
restriction was inherited verbatim[1] from Nix.

As such there's no bug here, although you could start a separate 
discussion about relaxing these restrictions if you like.

So what to do?  url-fetch defaults to the URL's basename as file name, 
but you can specify a different one.  For example:

   (source
     (method …)
     (uri …)
     (file-name (string-append name "-" version ".tar.gz"))
     (sha256 …))

Kind regards,

T G-R
