Firefox livelock/infinite loop on dragging "Most Visited"

[Tuomas Heino]

Binary package hint: firefox-3.5

Dragged "Most Visited" in FF (accidentally); as result it got in some kind of infinite loop / livelock.

Arrow keys, enter and mouse seem to be unavailable to other programs as well while it is in that locked state, so had to run ubuntu-bug outside of X. Alt-tab and writing in shell promts works otherwise, but with above mentioned input methods missing, that is not particularly useful for further diagnosis.

After switching back to X, only non-black thing in FF window is "Most Visited", and mouse icon is hand+chain. Clicking anywhere doesn't do anything.
