Public bug reported:

With the new PyQT version (e.g. 5.8), the QtWebKit and QtWebKitWidgets
are already deprecated, so the application is not runnable:

ImportError: cannot import name 'QtWebKit' (and QtWbKitWidgets - spread
through several project files)

So users with new PyQT library are not able to run the app at all.

I believe this problem is independent on the system, but just to be sure
here is the info:

1) Linux Mint 18.1
2) latest version available on 23.10.2017 (using the ppa:openlp-core/release repository)
3) The application won't run
4) I tried to change the imports in order to fix the app, but it will probably be necessary to use chromium widgets instead of the QtWidgets, which I did not do. Some of the import errors I got are:
