I can reproduce using "only" alt, i.e. calling the HUD for Firefox.
In my case, probably related to Bug #874260. It is 100% reproducable. When I open HUD, and get bookmark-results by hitting [tab] and typing something, this always happens. When I accidentaly open HUD, because of a mistyped alt-tab, this almost always happens, depending on what I type afterwards or whether I close HUD immediately.
Attached is a screencast of this bug in action and me, explaining it.
Workaround for me: killall unity-panel-service && killall hud-service
I have 2544 bookmarks and the SQLlite file "places.sqlite" is not corrupt. The bug remains when Optimizing (VACUUM) the SQLite file.
