A reproducible step is:
1. LANG=cs meld --help

LANG=ja reproduces it too.

A workaround for git mergetool is:
git config mergetool.meld.hasOutput true

*** Bug 1252882 has been marked as a duplicate of this bug. ***

Hello guys,

any progress on this one? It's quite annoying and still present in

LANG=cs meld-3.14.0-1.fc22.noarch

Regards,
Lukáš

I tried the latest version from sources https://github.com/GNOME/meld/commit/00b8efe0b1e6c38a3fadf7c9742e647925c1c055 and it works fine. Would it be possible to get the correct version in fedora?

This issue should be fixed then, right? There should be at least 3.14.1 in F22 currently.

After "dnf update" on F23 I have meld-3.14.0-2.fc23.noarch and the issue still exists:

```
$ LANG=cs meld --help
Couldn't set the locale: unsupported locale setting; falling back to 'C' locale

(process:20075): Gtk-WARNING **: Locale not supported by C library.
        Using the fallback 'C' locale.
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/meld/meldapp.py", line 72, in do_command_line
    tab = self.parse_args(command_line)
  File "/usr/lib/python2.7/site-packages/meld/meldapp.py", line 277, in parse_args
    if len(args) > 3:
UnboundLocalError: local variable 'args' referenced before assignment
```

as well as "git mergetool" simply hangs without any message, while "LANG=C git mergetool" lunches meld.

```
$ git mergetool
Merging:
README.rst

Normal merge conflict for 'README.rst':
  {local}: modified file
  {remote}: modified file
```

I tried the upstream version https://github.com/GNOME/meld/commit/bd7d1339c6b540130f93166238b18693528c06b5 and it worked well. I wanted to bisect it but all tagged versions worked for me. I tried to loop through all commits and all of them up to the end of the year 2014 worked well. I'm wondering what extra patches the "rpm" version contains...

It works for me with:
meld-3.14.1-1.fc23.noarch

Jaroslav, where you got it? I do not see that version in updates.

Hmm interesting, it seems that meld-3.14.1-1.fc23.noarch never got to updates and the koji build was deleted:
http://koji.fedoraproject.org/koji/buildinfo?buildID=689797

But it is in the dist-git:
http://pkgs.fedoraproject.org/cgit/rpms/meld.git/log/?h=f23

which is really weird.

Dominic could you build it and release it as an update?

This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '23'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 23 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.

Hello guys, I already moved to Fedora 25, where meld works well out of the box.
