Auto complete is a total mess for SIGNAL and SLOT since 4.7.0

Ever since 4.7.0 the auto complete shows every single member of the class instead of actual signals. Sometimes the signals can't even be found. Why? It makes it so frustrating to use I had to switch back to older versions.  Just look at the screenshots. All type of craps are shown as signals! I've been patiently waiting for it to be fixed but it's already 4.7.2 and it still shows the same. Tried 4.8 beta, same thing! please...
