Interesting... I just tried the same example and it didn't work for me at all. I can still copy it to the clipboard but the only thing that works is 'Paste Without Formatting' so I can only paste plain text. And X-Copy still doesn't work for me either.

So I just checked and I have 2 builds of Qt, 4.3.4 and 4.4, I was using the 4.3.4 version. It looks like 4.4 is doing the right thing now. Thanks for the response
