[Qt-creator] CMake: crash in cmakeproject.cpp

[Peter Kümmel]

Here I have a crash in cmakeproject.cpp when opening 
a cmake configuration.

Reading a bit the history of cmakeproject.cpp, 
I tried attached patch, then it doesn't crash any more 
but it also doesn't work any more:
no project nor files in the project explorer.
