Comment 8 for bug 1517589

The same happens in newborn 7146 nightly.

If I
- hover over the Ref
- push E to edit
- click Display - Invisible
- click OK on Footprint Text Properties dialog
- hover over the Ref again
- push E to edit
- click Display - Visible
- click OK on Footprint Text Properties dialog
- hover over the Ref again
- push M to move
... no double label after moving, no crash, all fine as expected

but when I
- hover over the Ref
- CLICK TO SELECT
- push E for set to invisible
- click OK on Footprint Text Properties dialog
- hover over the Ref again
- (this time doesn't count if I click to select or not)
- push E to edit
- click Display - Visible
- click OK on Footprint Text Properties dialog
- boom, crash!!
