Comment 2 for bug 158342

I can confirm this; I was specifically looking for it after my 7.06->7.10 upgrade and was surprised when it wasn't installed (python-qt4_4.3-2ubuntu7).

What's odd is that the packaging appears to have all the machinery in place to build the plugin; it just doesn't install it. Looking at previous package versions, it looks like 4.2-1 added support for the plugin, and 4.2-1ubuntu1 installed the plugin as part of python-qt4-*.deb. The next Ubuntu version, 4.3-2ubuntu1, removed a line from debian/python-qt4.install and consequently does not install it--but there's no mention of this in the changelog.

As noted in the previous comment, a one line addition to an *.install file appears to be all that's needed.
