probably during function definition in javascript file
Comment 8 Vladimir Riha 2012-07-23 10:27:58 UTC 
Somehow reproducible by pasting a large JSON code (~1k lines) into editor and repeating Undo/Redo

Comment 12 Svata Dedic 2012-08-01 08:11:41 UTC 
Actually triggered by moving to a closing brace when no mouse gesture was made in the editor. This is easily fixable in NbToolTip, but probably deserves an additional API call to show tooltips without trying to build them based on DocumentView + mouse position.
