I just checked that the problem persists even in newest git version. Also I have a feature request for circuit_plot. It would be very nice to have a way of making circuit plot display unfilled circles for controls which are triggered on qubit being in 0 state instead of state 1 (cf. Nielsen and Chuang book for examples of this eg. page 193 (fig. 4.16)). Without this feature you have to include a lot of NOTs in your circuit digram which makes it ugly and unreadable.
