I ran an strace and grepped for plugins and python and noticed the following
possibly missing files.

stat64("/usr/share/doc/python-qt4-doc/examples/designer/plugins/PyQt4",
0xbf9f4f74) = -1 ENOENT (No such file or directory)
open("/usr/share/doc/python-qt4-doc/examples/designer/plugins/PyQt4.so",
O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/usr/share/doc/python-qt4-doc/examples/designer/plugins/PyQt4module.so",
O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/usr/share/doc/python-qt4-doc/examples/designer/plugins/PyQt4.py",
O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/usr/share/doc/python-qt4-doc/examples/designer/plugins/PyQt4.pyc",
O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
stat64("/usr/share/doc/python-qt4-doc/examples/designer/plugins/sip",
0xbf9f2d24) = -1 ENOENT (No such file or directory)
open("/usr/share/doc/python-qt4-doc/examples/designer/plugins/sip.so",
O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/usr/share/doc/python-qt4-doc/examples/designer/plugins/sipmodule.so",
O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/usr/share/doc/python-qt4-doc/examples/designer/plugins/sip.py",
O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
open("/usr/share/doc/python-qt4-doc/examples/designer/plugins/sip.pyc",
O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)

I then installed the following additional packages and now it works, so I
think there is a missing dependency amongst the list below.

sudo apt-get install python-qt-dev python-qt4-dev python-sip4
python-sip4-dev

Should I file a bug (where)?

Thanks (for re-assuring me it worked on your end).
