I tried to profile, but guess I am stuck a bit. Interesting is that most times you see it lag and you interrupt it then, it hangs around in: #0 0x00007ffff3fc1a90 in operator< (k1=..., k2=...) at

I use current KF5 frameworks (yesterday build from scratch) and a Qt 5.2.0 build. Any clue what I could try to fix that would be really great.
