Bug Description

The installer crashes when I change the keyboard layout in Kubuntu 13.04:

Thanks for taking your time to report this issue and help making Ubuntu better.

This issue is really easy to reproduce:
1. Boot the kubuntu live cd.
2. Pick Deutsch (German) as the language and proceed through the installation.
3. When you get to the keyboard selector, select Switzerland in the language drop down.

This is also reproducible on Kubuntu Saucy alpha 1.

Btw, this might be connected with bug 1182784 which is also related to Swiss keyboards, but is triggered in a different way and presents a different error message, so it might be at least somewhat unrelated.

Bug 1182784 which I've mentioned above and seems related is supposed to be fixed in ubiquity 2.21.27 which is available in Ubuntu Wily. Could someone please retest this issue with an Ubuntu Wily image to see whether this issue is still reproducible, or whether it got fixed alongside the other.

Btw, please leave a comment when changing bug status. :) It was marked as triaged because it had been confirmed and also contained enough information for a developer to start looking at it, though it is not clear to me why it was changed back to confirmed. See https://wiki.ubuntu.com/Bugs/Bug%20statuses for more information.

the problem is not fixed. A installation from scratch with kubuntu-15.04-desktop-amd64.iso for country switzerland crashes again.

Ok, thanks for checking. Then we know that 15.04 is affected at least.

The fix for bug 1182784 is supposed to be in a newer version of Ubiquity. Strictly speaking, that is available in -updates in 15.04, though I don't believe the isos have been updated since the original release. So I think that would still have the bug anyways.

However, I tried with a daily snapshot of kubuntu wily werewolf, from [2]. This iso contained ubiquity 2.21.27 which is supposed to contain the fix. With that, I did not get a crash when selecting Switzerland in the drop-down menu. Could someone please double-check that it is no longer possible to trigger the crash? If so, it would mean that the issue is fixed for the upcoming 15.10.

(In addition to the daily build mentioned, the first alpha is supposed to be released shortly[3]. It mentions "for opt-in flavors", though I'm not sure whether this includes Kubuntu or not)
