Linux: Running Qt Creator when installation finished screws up permissions

When installing Qt Creator with the following command:

sudo ./qt-creator-linux-x86_64-opensource-2.8.0-beta.run

at the end of the installer, the option to run Qt Creator is automatically checked. However, running qtcreator now screws up permissions in my ~/.config/QtProject directory because the newly executed is ran as "sudo" (root).

So the next time I run the application as my normal user, all qtcreator config files have the root user and can't be re-written
