QGIS 2.14.3 Processing Dissolve error "local variable 'nElement' referenced before assignment See log for more details"

When I try to use Dissolve in Processing I get this error:

"local variable 'nElement' referenced before assignment See log for more details"

I have seen this problem reported in: https://hub.qgis.org/issues/14612

So then I did what is recommended by Alexander Bruy removed the processing folder from C:\Users\user.qgis2 however I still have the same problem, I did a Full Uninstall (delet all folders...) of Qgis and reinstalled from standalone installer QGIS-OSGeo4W-2.14.3-1-Setup-x86_64 but the problem persist.

I suspect that it is a bug...

PS: when I use the "Dissolve all" check, the process work, its only when I try to dissolve from a selected field that give me the error
