CodeModel: generated ui_*.h files seem to have a broken code model

Steps to reproduce:

• create a Qt Widget Application from QC's template
• build the project
• open the mainwindow.cpp file, hold Ctrl and click onto the include for the ui_mainwindow.h file

Current result:

• check the highlighting
  • seems to be almost broken
• try to click on one of the includes or one of the symbols holding Ctrl
  • some of the includes (normally the last 3?) aren't clickable at all
  • if you click an include you're following into a file of an include 3 ( ? ) lines below
  • if you click a symbol it depends on which you click if you're following to its declaration or not

Note: this seems to work fine, when using the clang code model, but appears to be broken for the Qt Creator built-in code model
