Is this really a bug fix? Doesn't look like a bug fix to me.
Also, every time you add Cc stable you should try to find the commit that introduced the bug. Sometime it's not possible because the bug existed before git was in use, but most of the time you'll find the offending commit using git blame.
A fixes tag should be formatted like that:
