Linux Mint 18 (Ubuntu 16.04)
Description
I get a segmentation fault when creating a new project while the first file with code appears (mainwindow.cpp). Similar segfault also occurs when opening an existing project/file and entering some blank lines.
It seems to be related to event handling in the code editor. I also tried several old versions of Qt and QtCreator, but always got segfaults. On Linux Mint 17 I never had these problems, so I think it's somehow related to Mint 18 / Ubuntu 16.04.
I installed QtCreator and Qt with `qt-unified-linux-x64-2.0.3-1-online.run`
Thread 1 "qtcreator" received signal SIGSEGV, Segmentation fault.
