#1528 Unsupported Locale Setting in KDE - Ubuntu

1. Yesterday I installed Taskcoach for the first time in kubuntu using ppa.
2. It started using it without any problems.
3. During the afternoon I changed the country to Germany in the KDE Settings.
4. I also changed to measurement system to use the metric one.
5. I also installed the python module easy_install
6. Yesterday I saved my taskcoach file before shutting down my laptop.
7. Today I cannot start Taskcoach. When I try it using the terminal, I get the following error message:

arobirosa@creation:~$ taskcoach.py

(process:3731): Gdk-WARNING **: locale not supported by C library

(process:3731): Gtk-WARNING **: Locale not supported by C library.
        Using the fallback 'C' locale.

    return _setlocale(category, locale)
locale.Error: unsupported locale setting

• I tried changing the country of KDE back to USA because I got the same stacktrace.

I attached the taskcoach file and my configuration file.

Above you will find more information which may be useful to reproduce the error. I am a Java developer so I could also help you by running special modified versions of Taskcoach.

Thanks in advance!

I set the language in the following setting of the ini file and I get the same stackstrace:

[view]
language_set_by_user = English (US)
language = English (US)

Before this change, this were empty.

Thanks!

For the record. The cause of the error was a non standard locale in my machine:

arobirosa@creation:~$ locale
LANG=en_DE.UTF-8
LANGUAGE=en
LC_CTYPE="en_DE.UTF-8"
LC_NUMERIC=en_DE.UTF-8
LC_TIME=en_DE.UTF-8
LC_COLLATE="en_DE.UTF-8"
LC_MONETARY=en_DE.UTF-8
LC_MESSAGES="en_DE.UTF-8"
LC_PAPER=en_DE.UTF-8
LC_NAME=en_DE.UTF-8
LC_ADDRESS=en_DE.UTF-8
LC_TELEPHONE=en_DE.UTF-8
LC_MEASUREMENT=en_DE.UTF-8
LC_IDENTIFICATION=en_DE.UTF-8
LC_ALL=

I wanted to have my KDE in English and use the locale for Germany. Unfortunately, this doesn't work with Taskcoach and Perl.

So I changed the language to German in the KDE konfiguration and restart it, and now TaskCoach is working. My current locale is de_DE (German in Germany).

I believe that TaskCoach didn't work due to the locale configuration of Python. Due to this, no changes in Taskcoach are necesary and this ticket could be closed with "won't fix" resolution.

Cheers!

I dunno. Whatever the reason we shouldn't crash at startup. There's probably a way to fallback on the C locale when this happens; I'll take a look.

Thanks for the detailed report!

[Jérome Laheurte]

This bug should be fixed in the latest release of Task Coach. Can you please install the latest release of Task Coach and confirm that this bug has indeed been fixed?

Thanks, Task Coach development team

Hi Jérome,

I was able to reproduce the error with the old version but Taskcoach 1.4.0 starts without any problem.

This issue is solved.

Thanks for your quick fix!
