Qt Creator directly crashes at startup

When trying to start QtCreator installed from the x86_64 linux installer (qt-creator-opensource-linux-x86_64-3.3.0-rc1.bin) it immediately crashes without even showing a main window:

$ ./qtcreator.sh
Segmentation fault (core dumped)

I have QtC 3.2.2 running without problems, which I also installed from the linux installer.

LDD output:
