Comment 3 for bug 898666

Here is the result of more tests to try to find what triggers this problem:

The following factors had no effect on the problem (Ubiquity crashed each time at the same point):
- using a different proxy (we have currently 2 in my corporate network)
- installing the 32 bit or the 64 bit version of Kubuntu 11.10
- starting with a disk already partitioned (and reusing those partitions) or a disk with no partition and creating them during install
- installing in English instead of if French
- installing on another machine

Only this factor had an effect:
- installing Ubuntu 11.10 64 bit instead of Kubuntu 11.10 64 bit was successful

A strange fact:
- I could install Kubuntu 11.10 64 bit successfully on the same machine shortly after it was released. Now this is no more possible.

Possible explanation:
- could a recent change in a repository used by Kubuntu but not by Ubuntu be the reason for the current problem?
