1. Run Creator with enabled built-in code model.
2. Create a new Qt Widgets Application project.
3. In the main function, type "unsig".
   The proposal window will show "unsigned", "Q_COMPILER_UNICODE_STRINGS" and "Q_STDLIB_UNICODE_STRINGS". While the first is obviously correct, the latter two don't seem right to me.

Only "unsigned" should be proposed as code completion. In Creator 4.10, this works correctly.
