Qml debugging: breakpoint in one .qml but debugger stops in another file

If project has 2 qml files with identical naming, the debugger seems to get a bit confused and breakpoints set in one of the files may result in the debugger stopping in the other instead.

Steps to reproduce the problem:

1. Open the attached project in Qt Creator
2. Set breakpoint in Page1Form.ui.qml at line 16
3. Debug
   => debugger will stop in subdirectory/Page1Form.ui.qml at line 16 instead

This problem doesn't seem to be affected by the option "set breakpoints using full absolute path". The debugger is stopping in the wrong file regardless.
