Bug 480724 – Localization broken in kde-native dialogs used in Qt-based applications

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Egor Y. Egorov 2013-08-12 12:58:06 UTC]

Build test Qt-application:
#include <QtGui>
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    bool ok;
    QFileDialog::getExistingDirectory();
    QColorDialog::getColor ();
    QFontDialog::getFont(&ok);
    QTimer::singleShot(1000, QApplication::instance(), SLOT(quit()));
    return a.exec();
}

and run in KDE environment.


Reproducible: Always

Steps to Reproduce:
Build test Qt-application:
#include <QtGui>
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    bool ok;
    QFileDialog::getExistingDirectory();
    QColorDialog::getColor ();
    QFontDialog::getFont(&ok);
    QTimer::singleShot(1000, QApplication::instance(), SLOT(quit()));
    return a.exec();
}

and run in KDE environment with not default locale (ru_RU.UTF-8 in my case)
Actual Results:  
Dialogs are not localized.

Expected Results:  
Dialogs are localized.


In strace log we can see:
access("/home/eegorov/.kde4/share/locale/ru/LC_MESSAGES/kfilemodule.mo", R_OK) = -1 ENOENT (No such file or directory)
access("/usr/share/locale/ru/LC_MESSAGES/kfilemodule.mo", R_OK) = -1 ENOENT (No such file or directory)
access("/home/eegorov/.kde4/share/locale/ru_RU/LC_MESSAGES/kfilemodule.mo", R_OK) = -1 ENOENT (No such file or directory)
access("/usr/share/locale/ru_RU/LC_MESSAGES/kfilemodule.mo", R_OK) = -1 ENOENT (No such file or directory)
access("/home/eegorov/.kde4/share/locale/ru/LC_MESSAGES/kfilemodule.mo", R_OK) = -1 ENOENT (No such file or directory)
access("/usr/share/locale/ru/LC_MESSAGES/kfilemodule.mo", R_OK) = -1 ENOENT (No such file or directory)
access("/home/eegorov/.kde4/share/locale/ru_RU/LC_MESSAGES/kfilemodule.mo", R_OK) = -1 ENOENT (No such file or directory)
access("/usr/share/locale/ru_RU/LC_MESSAGES/kfilemodule.mo", R_OK) = -1 ENOENT (No such file or directory)
access("/home/eegorov/.kde4/share/locale/ru/LC_MESSAGES/kfilemodule.mo", R_OK) = -1 ENOENT (No such file or directory)
access("/usr/share/locale/ru/LC_MESSAGES/kfilemodule.mo", R_OK) = -1 ENOENT (No such file or directory)
access("/home/eegorov/.kde4/share/locale/en_US/LC_MESSAGES/kdelibs4.mo", R_OK) = -1 ENOENT (No such file or directory)

=> workaround:

mkdir -p ~/.kde4/share/locale/ru/LC_MESSAGES/
cd ~/.kde4/share/locale/ru/LC_MESSAGES/
ln -s /usr/share/locale/ru/LC_MESSAGES/kdialog.mo kfilemodule.mo

After this all localized fine.

I do not know, this is gentoo bug or upstream bug. But maybe it makes sense to install links kfilemodule.mo -> kdialog.mo in /usr/share/locale/<lang>/LC_MESSAGES/ by kde-base/kde-l10n ebuld?

[Comment 2 Johannes Huber (RETIRED) 2013-11-03 12:59:33 UTC]

Is this still valid with testing qt (4.8.5) and kde (4.11.2) version?

[Comment 3 Egor Y. Egorov 2013-11-03 13:38:14 UTC]

Yes. Bug is still with qt-4.8.5 on kde-4.11.2

[Comment 4 Egor Y. Egorov 2014-04-30 06:04:52 UTC]

Bug is still with qt-4.8.5 on kde-4.13.0

[Comment 5 Michael Palimaka (kensington) 2014-05-01 11:24:07 UTC]

This should probably go upstream I guess.

[Comment 6 Johannes Huber (RETIRED) 2014-07-25 19:45:32 UTC]

Please report this upstream. This looks not like an packaging issue. If it turns out that this is a Gentoo specific problem, please re-open this bug.
