Comment 2 for bug 1525357

Oh, I didn't intend for anyone to work on this now! I filed it while I was thinking about it so it could be considered later. (I also originally thought we were going to disable qDebug in this release, but we're actually not planning to do so any time soon, hence the 'Low' priority and no milestone targetted.)
The reason we would disable it is to prevent the overhead of printing messages to the console and into the log file.
