Creator crashes when creating Qt Quick App after Qt Quick UI without a valid kit

Steps to reproduce:

• start Creator with clean settings (have no Qt5 in PATH, I've got a Qt4 in PATH if this matters)
• create a Qt Quick UI (from New Project wizard) using Quick 2.0
• create a Qt Quick Application using Quick 2.0 or Controls - this should now tell you there's no valid kit
• on the Kit Selection page click on 'options' link
• add Qt 5 version and create a kit out of it, hit OK
• application to be created should have the newly create kit automatically selected
• click 'Next' and 'Finish'

Current behavior:

• Creator crashes
