I just updated our package to the most recent one, 3.28.0, and it now
builds. However, I forgot to test it, and running it fails with
Traceback (most recent call last):

ImportError: No module named QtWebKitWidgets

So this needs to be corrected with respect to the disappearance of
QtWebKitWidgets from Qt, I will have a look now. (So far, I think there
is no point in reverting the commit to get back from a non-working to
a non-compiling calibre...)
