I've noticed this when I started the wrong Creator (wrong version) and hit Ctrl-Q to close it.
Creator 2.6, sha1 2910233.
Based on Qt5, sha1 749b83f.
- Creator restores the last session on startup.
- Last session contains a big project, like qtcreator itself.
How to reproduce
- Start Qt Creator
- As soon as the window gets the focus, hit Ctrl-Q.
The window will close and some seconds later creator crashes.
