in the nightly build 20090620, and in the last few nightlies for me, the history menu's contents "disappear" temporarily when your mouse hovers over the item for "Restore from last session."

this happens every time. the items come back if you re-open the History menu though.

1. click history menu
2. hover mouse over "Restore from last session"
3. watch last visited pages disappear from History menu
Actual Results:  
the history items disappeared from the menu

Expected Results:
