+Subject: [PATCH] Make PyQt checks in tests more specific
+
+Test whether the widgets module can be imported rather than 'PyQt?'
+in general.  The latter gives false positives if PyQt is uninstalled
+but there are leftover subpackages such as qscintilla.  In this case,
+Python 3 imports 'PyQt?' as a namespace.
