ubiquity installer crashes at language select

Status changed to 'Confirmed' because the bug affects multiple users.

The problem here is that we're reading 512 bytes at a time from debconf and trying to decode it to text; this fails if a 512-byte boundary happens to fall in the middle of a Unicode character. Oops.

This bug was fixed in the package ubiquity - 2.11.1

---------------
ubiquity (2.11.1) quantal; urgency=low

  * Fix handling of pipes to update-apt-cache.
  * Sync up scripts/clock-setup-apply with changes in clock-setup 0.110.
  * Only decode bytes read from debconf once we have a complete line
    (LP: #1001542).
  * Remove a couple of unused attributes.

Hi
Yes updated ubiquity 2.11.1 does solve the problem, at least for me,
in Ubuntu 12.10, I don't know about Kubuntu, I downloaded and tried
the daily build for ubuntu with the new ubiquity I think it was
yesterday, and all went normally, I don't recall if Kubuntu does a
daily build or if they do a weekly, but you can check the package list
and see if the new 2.11.1 version of ubiquity is listed instead of the
2.11.0 version which had the bug. Good Luck.

according to http://cdimage.ubuntu.com/kubuntu/daily-live/ they update daily and I have the latest iso. According to the attachment I uploaded the version of ubiquity is 2.11.1

@cpatrick08: Could you please file a new bug for this? It's a different problem, apparently in code specific to the KDE frontend. It'd be easier for me to track it separately.

Well, never mind; I've committed a fix for 2.11.2. Thanks for the report.
