Relax or regularize in texture editor broken - since 2014

[druitre]

Hi,

I reported a bug on this but would like to check if anyone else can confirm:

-open new scene
-create sphere (or any geo)
-create texture projection (any type)
-open texture editor and select some verts
-tools>regularize (or relax, both do the same)
-adjust iterations or power slider

BOOM! The UV's disappear and are gone 'till I freeze or remove the operator and refresh the window. In 2013SP1 it's still working, in 2014 and 2014SP1 I get this buggy thing.

No repro for me in 2014
