Also occurred for me when clicking Insert in the LibreOffice Calc global menu bar. Program and Unity frozen temporarily, then kicked back the crash report.

[Clint Byrum (clint-fewbar)]

this happens constantly to me, seemingly at random, in unity-2d and regular unity.

This should be fixed with the next ido release and the retooling of the idorange code.
