Follow link under cursor only works for the first time

When Ctrl+Clicking on e.g. a method definition, the declaration is only opened for the first time.

1. Open qtcreator-git/src/libs/utils/fancylineedit.cpp.
2. Ctrl+Click on "setValidationFunction" in "void FancyLineEdit::setValidationFunction(const FancyLineEdit::ValidationFunction &fn)".
3. Notice how the declaration is opened in the header file.
4. Close the header file again.
5. Perform step 2 again.

Actual result: The declaration in the header file is not opened. Not even the header file is opened.

Expected result: Same as in step 3.
