      Description

      1. Build current Qt Creator from the 4.0 branch against an installation of Qt 5.6.0 from the official packages
      2. Start Qt Creator
      3. Activate the help mode
      • The main area of the help mode is gray
      • Activation of the help mode generates:

      /home/nik/usr/qt-5.6.0-install/5.6/gcc_64/libexec/QtWebEngineProcess: error while loading shared libraries: libQt5WebEngineCore.so.5: cannot open shared object file: No such file or directory

      Workaround for a working help mode is the env var QTC_HELPVIEWER_BACKEND=textbrowser.
