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

[Zorael]

Binary package hint: ubiquity

Trying to install Kubuntu 11.04 on an MSI Wind U100 rebrand netbook.

After booting the live media I was automatically presented with the netbook workspace formfactor, but instead of changing it to the normal desktop workspace I thought I'd give it a try.

The installer crashed after I finished manually partitioning with the attached python backtraces. I retried it twice and it was quite reproducible. After switching to the desktop workspace (and running ubiquity from a terminal with debugging enabled), I got past that step and the installation finished successfully.

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!
