I think Bug QTCREATORBUG-13730 reappeared again.

I wanted to import a scons project, and after the last click on next creator crashed. the 4 project files were generated, though when i tried to open them, it again crashed. later I tried with some random .cpp and .h files, and it also crashed. there where just a few files arround, so to reproduce any main.cpp file should be enough.

i later checked Options -> Build & Run -> Kits. There were 2 Kits in Auto-detected, msvc 2013 and mingw. I made msvc default and thereafter creator didn't crash anymore. so when trying to reproduce, be sure that there is no default kit.
