do-release-upgrade crashes while updating from 13.04 to 13.10 when locale is ru-RU.UTF8

[Ilya Loginov]

Application crashes with the following stacktrace:

Error in sys.excepthook:
Traceback (most recent call last):
  File "/tmp/ubuntu-release-upgrader-6agiri/DistUpgrade/DistUpgradeViewText.py", line 107, in _handleException

    print(twrap(summary))
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-8: ordinal not in range(128)

Original exception was:

    sys.exit(main())
  File "/tmp/ubuntu-release-upgrader-6agiri/DistUpgrade/DistUpgradeMain.py", line 230, in main

    print(msg)

When I start do-release-upgrade with LC_ALL=C all works fine.

My locale is:

LANG=ru_RU.UTF-8
LANGUAGE=
LC_CTYPE="ru_RU.UTF-8"
LC_NUMERIC="ru_RU.UTF-8"
LC_TIME="ru_RU.UTF-8"
LC_COLLATE="ru_RU.UTF-8"

I get the following (below). It is strange because I allready upgraded 3 machines with same locale (NL).

ferry@eeepc:~$ do-release-upgrade -m desktop -f DistUpgradeViewKDE -d
Er wordt gecontroleerd of er een nieuwe Ubuntu-uitgave is

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

For KDE the exact command line to get passed this bug is:
 LC_ALL=C.UTF-8 sudo do-release-upgrade -m desktop -f DistUpgradeViewKDE

This gives the following:
Er wordt gecontroleerd of er een nieuwe Ubuntu-uitgave is
Ophalen:1 Handtekening opwaardeerprogramma [198 B]
Ophalen:2 Opwaardeerprogramma [1136 kB]
1136 kB opgehaald in 0s (0 B/s)
'saucy.tar.gz' tegen 'saucy.tar.gz.gpg' verifiëren
âsaucy.tar.gzâ wordt uitgepakt

(note strange char's)

Then follows some repeated:
Fontconfig warning: ignoring C.UTF-8: not a valid language tag

So, not 100% language tag, but get's me passed the crash point.

While doing ppa-purge on xorg-edgers I noticed the following warnings that may be related to my problem:
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = "nl:en_US:en",
        LC_ALL = (unset),
        LANG = "nl_US.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory

No idea what this means. Maybe be missing a dependancy?
