QtCreator crashes on malformed .pri

With the latest QtCreator, when I open a project that imports a malformed .pri, the whole program crashes.

With other versions of QtCreator, this doesn't happen, and the program just warns me that there is a syntax error when I try to compile the project. 2.0.94 (2.1.0-rc1) works fine, and IIRC, 2.1 worked fine as well.

I've tracked down the error to the minimalistic .pro attached.

Behaviour:

• If I try to open it with QtCreator, the program crashes
• If I add the mission brace and open it with QtCreator, it works
• But if inside QtCreator I remove the brace and save again, after a few seconds the program crashes
