Fabio, I'm confident that the mouse isn't to blame, middle-click worked fine on other windows to send-to-bottom and to paste from the selection buffer when this happened, and restarting the clients in question allowed it to work on them again.
I've run the apport-collect command, though the intervening three weeks might have been enough time to overwrite anything that might have been useful from the time of this bug report.
