I haven't had time to try this, but I believe this isn't a bug, it's just that you didn't supply --no-tags.

"But I want some tags!", yes, that's not what --no-tags does, see the 2nd paragraph of the DESCRIPTION section of "git-fetch".

I.e. it got stuff you asked for, but also tags pointing at the main history, --no-tags will stop that, at which point you can *also* fetch tags, just with the refspec.
