[Qt-creator] Crash in Cpp editor

[Marc Wathelet]

I'm using Qt-creator
qt-creator-f867061d5b5b5bb440ab42923462518973c73817.tar.gz (version 0.9.2)
I get always this segmentation fault when I display the attached file. I
tried inside its project and standalone, I get exactly the same backtrace.
If you need more information, I can recompile Qt-creator with debug
symbols and trace whatever variable.
