+    In PySide, using Python objects as userData in QComboBox causes
+    Segmentation faults under certain conditions. Even in cases where it
+    doesn't, findData does not work correctly. Likewise, findData also does not
+    work correctly with Python objects when using PyQt4. On the other hand,
+    PyQt5 deals with this case correctly. We therefore patch QComboBox when
+    using PyQt4 and PySide to avoid issues.
