[Alexander Belchenko (bialix)]

And there is no way to workaround this, because setting env variable LANGUAGE to either C or en does not help - the same error.

[Alexander Belchenko (bialix)]

Sorry, forget the last comment, that's my fault, I've typed LANGAUGE rather than LANGUAGE.

So, actually the only woirkaround is to force English locale.

[Martin Packman (gz)]

Huh, TextProgressView straight up doesn't support non-ascii text. Setting BZR_PROGRESS_BAR=none is also a reasonable workaround for this particular issue, for now people want to just disable localisation completely as there are still a selection of bugs like this,

    including this traceback and a description of the problem.

It seems all commands that works with working tree are affected.

[Alexander Belchenko (bialix)]

OK, another workaround is to use QBzr dialogs instead of plain bzr commands. QBzr works correctly with unicode.

[Alexander Belchenko (bialix)]

I think this bug is Critical, although there are several workarounds. Should we edit the description of the bug report and provide information on workarounds?

[Chris Halse Rogers (raof)]

Hello Alexander, or anyone else affected,

Accepted bzr into precise-proposed. The package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Andrew Starr-Bochicchio (andrewsomething)]

Hi all,

This is the last bug in the proposed bzr SRU to precise that hasn't had the fix verified. Could someone experiencing this confirm that the version in precise-proposed resolves this issue on Ubuntu for them? Or someone provide instructions to reproduce this?

Thanks!

[Martin Packman (gz)]

This might be a little annoying to reproduce, as it requires both a non-english locale that translates a progress update string (and uses a non-ascii character), and to do a slow enough operation that the progress gets displayed.

So, something like:

    $ locale -a
     # verify that ru or ja locale is available
    $ bzr branch -r-40 lp:qbzr test_branch
     # get not quite all of a project so pull will get new changes and update tree
    $ LANG=ja_JP.utf8 bzr pull -d test_branch
     # should see at least one progress message not in english, and no traceback

[Martin Packman (gz)]

So, it turns out that due to a packaging bug Ubuntu doesn't actually install .mo files, whereas Debian does. Therefore I'll verify this bug on the grounds it's not reproducible with the precise-proposed package.

Package's in main have their .mo file stripped at build time and moved
into language-packs for iso space issues. For instance,
'/usr/share/locale-langpack/ru/LC_MESSAGES/bzr.mo' is found in the
package 'language-pack-ru-base'

[Launchpad Janitor (janitor)]

This bug was fixed in the package bzr - 2.5.1-0ubuntu1
