It works fine for me, but there is a slight delay when pressing Ctrl-C before it gets responsive again and data can be pasted. Might be then that your copy crashes.
It seems from the clipboard content that it produces XML data while copying objects. Might be something about converting “whatever it handles on the canvas” to XML and shoving it onto the clipboard that causes the delay.
I’m guessing the developers will hear about it, if it’s a wide spread issue.
It could of course also be something strange going on with your machine.
