(Get the code!)
It happened again here. I can confirm what Jani's saying: while launcher seems to be wedged, it still responds to desktop events like alerts/wiggles and applications being launched and closed. Clicking an icon triggers displaying the name tooltip (which is no longer triggered by hovering), but nothing else.
Possible clue: This time, i was alert enough to observe that when the bug was triggered, it happened while my system was busy swapping heavily enough for mouse cursor movement to become jerky. I suspect that the accidental "drag" may have been a normal click + mouse movement whose sequence of events got delayed or interfered with by the disk I/O. I'm not familiar with the code, but would an unusual or unexpected sequence of mouse / click events be able to put the launcher into this bad state?
Another note: I was using the NVIDIA driver this time, not the Nouveau one, so the problem doesn't seem to be related to them.
