'rating:e' as tag while uploading gives weird result

http://trac.donmai.us/ seems down. So I'm not sure where I should go.

Anyway, for exactly what happened: I tried to use 'rating:e' as one of the tags to set a post to explicit while uploading. That works as the rating on the post page shows 'Explicit'; however, the *tag history* instead gives me the default rating and tag 'rating:q'.

This is reproducible.

Thanks,
