Fixed! Not yet on committed. Coming soon.
Here is my latest report to PyQt:
QQQ
It turns out that the difference in behaviors in the QTreeWidget on
the XP and Linux platforms was the result of a call to
QTreeWidget.scrollToItem in an item-expanded event handler. On XP,
this scrolls only vertically; on Linux, it may scroll in either
direction. Removing this call makes the QTreeWidget usable on Linux.
I'm tempted to call this the most serious bug I've found with PyQt,
which is another way of saying that PyQt has been very very good to me
:-)
