[natty] kde_components/PartitionModel.py crashes if installer run in plasma netbook workspace

That really should not have anything to do with the kind of Plasma shell.

Also that particular backtrace does not make much sense unfortunately :/

relevant lines:

class TreeItem:
    def __init__(self, data, controller=None, parent=None):
        self.parentItem = parent

    def row(self):
        if self.parentItem:

Now I just tested whether an assignment with None would result in such an error, though it does not.
Equally the other part of the backtrace is super confusing, and might or might not be related.

        childItem = index.internalPointer()
        parentItem = childItem.parent()

All in all I am pretty clueless on this, and can neither confirm nor fix this issue. Perhaps someone more knowledgeable in python can find the problem.

Thanks for the report anyway.

I just did a manual partition in 12.04 just fine (though I did find another bug not related to this on the desktop install process). Have you tried on any of the later releases (11.10, 12.04 alpha - beta next week I think)?

Thanks!
