Comment 2 for bug 67394

That's exactly the point, I cannot reproduce this either. As I.ve indicated, I was working intensively with Edgy, filing bugs ;-(, and as an effect, I cannot recall exactly what seems to be the crucial step in which the clipboard functionality began to fail.

To answer your question: after I filed the bug, it didn't happen anymore. I try to keep this problem in mind, but for now, it's almost impossible to do anything about it because it's not reproducable at this moment.
