[PyQt] pyuic4 assign invalid roles to labels and fields in Form layout

[Marián Kyral]

Hello,
I've folloving ui file:

<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
 <class>Form</class>
 <widget class="QWidget" name="Form">
  <property name="geometry">
   <rect>
    <x>0</x>
    <y>0</y>
    <width>400</width>
    <height>300</height>
   </rect>
  </property>
  <property name="windowTitle">
   <string>Form</string>
  </property>
  <layout class="QFormLayout" name="formLayout">
   <item row="0" column="0">
    <widget class="QLabel" name="label">
     <property name="text">
      <string>Jablka:</string>
     </property>
    </widget>
   </item>
   <item row="0" column="1">
    <widget class="QLineEdit" name="lineEdit"/>
   </item>
   <item row="1" column="0">
    <widget class="QLabel" name="label_2">
     <property name="text">
      <string>Hrušky:</string>
     </property>
    </widget>
   </item>
   <item row="1" column="1">
    <widget class="QLineEdit" name="lineEdit_2"/>
   </item>
  </layout>
 </widget>
 <resources/>
 <connections/>
</ui>

pyuic4 generates following code:
# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file 'form_layout.ui'

from PyQt4 import QtCore, QtGui

try:
    _fromUtf8 = QtCore.QString.fromUtf8
except AttributeError:
    _fromUtf8 = lambda s: s

class Ui_Form(object):
    def setupUi(self, Form):
        Form.setObjectName(_fromUtf8("Form"))
        Form.resize(400, 300)
        self.formLayout = QtGui.QFormLayout(Form)
        self.formLayout.setObjectName(_fromUtf8("formLayout"))
        self.label = QtGui.QLabel(Form)
        self.label.setObjectName(_fromUtf8("label"))
        self.formLayout.setWidget(0, QtGui.QFormLayout.FieldRole, self.label)
        self.lineEdit = QtGui.QLineEdit(Form)
        self.lineEdit.setObjectName(_fromUtf8("lineEdit"))
        self.formLayout.setWidget(0, QtGui.QFormLayout.LabelRole, self.lineEdit)
        self.label_2 = QtGui.QLabel(Form)
        self.label_2.setObjectName(_fromUtf8("label_2"))
        self.formLayout.setWidget(1, QtGui.QFormLayout.FieldRole, self.label_2)
        self.lineEdit_2 = QtGui.QLineEdit(Form)
        self.lineEdit_2.setObjectName(_fromUtf8("lineEdit_2"))
        self.formLayout.setWidget(1, QtGui.QFormLayout.LabelRole, self.lineEdit_2)

        self.retranslateUi(Form)
        QtCore.QMetaObject.connectSlotsByName(Form)

    def retranslateUi(self, Form):
        Form.setWindowTitle(QtGui.QApplication.translate("Form", "Form", None, QtGui.QApplication.UnicodeUTF8))
        self.label.setText(QtGui.QApplication.translate("Form", "Jablka:", None, QtGui.QApplication.UnicodeUTF8))
        self.label_2.setText(QtGui.QApplication.translate("Form", "Hrušky:", None, QtGui.QApplication.UnicodeUTF8))

As you can see, labels have assigned FieldRole and fields have assigned LabelRole.

        self.formLayout.setWidget(0, QtGui.QFormLayout.FieldRole, self.label)
        self.formLayout.setWidget(0, QtGui.QFormLayout.LabelRole, self.lineEdit)

This problem is at least in pyqt 4.8.0 and 4.8.1.
