Still, there is no proof that this is a bug.

Such message may appear when the FTP client requests a new data channel
without opening the previously requested one.

There is one case, when it happens quite naturally: client sends an
active FTP request, but the server refuses it. Then the client reverts to
passive FTP and repeats the data channel request.

A tcpdump of the FTP command session could help to find out where's the
problem.
