Links to modules are broken in ALL Qt 5.0 class ref pages

Related to QTWEBSITE-457

This error applies to all Qt 5.0 class ref pages, but illustrated here with one example: http://qt-project.org/doc/qt-5.0/qaudiooutput.html

ISSUE
At the top of the class reference page is a 'hierarchy bar':
Home > Docs > Qt library 5.0 > QtMultimedia > QAudioOutput

Clicking on "QtMultimedia" in the 'hierarchy bar' leads to a 404 error.

CAUSE
The module page was relocated from
http://qt-project.org/doc/qt-4.8/qtmultimedia.html
to
http://qt-project.org/doc/qt-5.0/qtmultimedia-module.html

but the 'hierarchy bar' was not updated to reflect this. The Qt 4.x class refs are fine.
