    Description

      I have opened cmake project. I open another, open the source file from that project and try to edit it. Qt Creator then crashes with

      SOFT ASSERT: "modelManager" in file /work/build/qt-creator/src/plugins/cmakeprojectmanager/cmakeproject.cpp, line 323
SOFT ASSERT: "modelManager" in file /work/build/qt-creator/src/plugins/cmakeprojectmanager/cmakeproject.cpp, line 323
ConnectionServer error: "QLocalSocket: Remote closed" "/tmp/QtCreator-zKELOF/ClangBackEnd-7526"
Segmentation fault (core dumped)

      Backtrace from core dump looks like this
