I can't test on another version than 1.0.7 but as I can't find anything on this bug I think that is applicable on the latest version.
The use of the function tableWidget create a crash of the application.

You can try this example :

from PySide import QtGui

table = QtGui.QTableWidget()
table.setRowCount(1)
table.setColumnCount(1)

item = QtGui.QTableWidgetItem("test")
table.show()
table.setItem(0,0, item)

print item.tableWidget()
print table
# table.setItem(0,0, QtGui.QTableWidgetItem("test2"))
# table.removeRow(0)

qtapp.exec_()

The function return the good memory adress but if you try to use the table after calling item.tableWidget() your program close without exception.
