If I try to use QTest.mouseClick on a QTreeWidget it raises an assert from the C++ library.

tree.headerItem().setText(2,"")
item = QtGui.QTreeWidgetItem(tree)
item.setText(0,"a")
item.setText(1,"b")
item.setText(2,"c")
QTest.mouseClick(tree,Qt.LeftButton,pos=tree.visualItemRect(item).topLeft())
ASSERT: "QTest::testLogger" in file qtestlog.cpp, line 334
Abort trap: 6
I'm using PySide 1.2.2 and I've tried this on both OS X (10.9.3) and Windows7, both with the exact same result.
Am I doing something incorrect or did I discover a PySide bug (I'm fearing that the latter is the case)?
UPDATE:
The suggestion from @Trilarion gave me an idea. I tried adding a parent to the QTreeWidget. Doing that resolved the ASSERT, however the QTreeWidget does not seem to register the emulated click at all.

#Sanity check to make sure that the button is registering the click
QTest.mouseClick(button,Qt.LeftButton)
#Overkill click test, try clicking the tree on every point in a 1000 x 1000 grid
click()
button was clicked
StartClick
EndClick
I also tried running the above code in a unit test, didn't change the outcome.
