I am not real sure this is exactly what you are looking at. They are saying that under Windows, the automatic file extensioning is done by default for you and that on Linux you have to do what you just did. However, I do not see any mention of the setDefaultSuffix function. I would still go ahead and start a new ticket since they do not mention the defaultSuffix in this report. But that is just my opinion...
