Installer crashed while choosing partitions

[vedran]

While installing ubuntu 6.06 LTS in "Select a disk" page I selected "Manually edit partition table" and clicked continue. After about 1 min of scanning I get a "Prepare partitions" page. It is empty except text "Make sure to allocate space for a root partition ...", under that "Step 5 of 6" and buttons "Back" and "Continue". I click "Continue" once and nothing happens. When I click it again installer crashes and I get the following message:

Traceback (most recent call last):
  File "/usr/bin/ubiquity", line 130, in ?
    install(sys.argv[1])
  File "/usr/bin/ubiquity", line 55, in install
    ret = wizard.run()
  File "/usr/lib/python2.4/site-packages/ubiquity/frontend/kde-ui.py", line 311, in run
    self.process_step()
  File "/usr/lib/python2.4/site-packages/ubiquity/frontend/kde-ui.py", line 731, in process_step
    self.gparted_to_mountpoints()
  File "/usr/lib/python2.4/site-packages/ubiquity/frontend/kde-ui.py", line 804, in gparted_to_mountpoints
    print >>self.qtparted_subp.stdin, "apply"
AttributeError: 'NoneType' object has no attribute 'stdin'

This happens every time I launch installer.

Thanks for your report, which is also bug 47194. The program used for advanced partitioning, qtparted, appears to have crashed. The version of the installer present in Kubuntu 6.06.1 deals with this more gracefully. If you can reproduce the qtparted crash by running it directly from K Menu -> System, then please file a separate bug against qtparted.
