Problem description

Application ends up in unusable state when undoing operation when Measure was active.

Initial part:

After adding chamfer and measuring the selected edge:

While Measure is active, Ctrl-Z to undo the chamfer:

When trying to close the Measure:

Full version info

Basically:
- have a circular hole in your part
- create chamfer on the edge on that hole
- use measure tool on that edge
- use Ctrl-Z to undo the chamfer operation (while Measure is still active)
- tada! it is now stuck in Measure, can't close it, have to restart FreeCAD

It is happening in both Part and Part Design, also for simple straight edges (chamfer, measure, undo, stuck). 
It is possible to close the file and create new one, but the program is already borked. Only restart helps.
