I can confirm this. I was just going to post my findings and then saw this response. I switched from nouveau to the proprietary nvidia drivers and this "fixed" the problem with kdevelop for me. I ran into the same issue, running as a new user didn't help. As a crude test I temporarily removed the kdevclangsupport.so plugin which is linked against LLVM-3.8 and I could then start kdevelop again. I then checked what part was linked against LLVM-3.9 and this appeared to be nouveau_dri.so (loaded by libGL.so.1). I then switched to the proprietary nvidia driver and the problem was gone. (Of course not a real solution; indeed having the clang plugin linked against LLVM-3.9 should fix the problem for real). Kind regards, Martijn
