The "Document Viewer" window title shows untranslated in my Spanish desktop, albeit it's translated in Launchpad since 2006-03-18:

  https://translations.launchpad.net/ubuntu/lucid/+source/evince/+pots/evince/es/91/+translate

and the translation is included in the evince.mo file:

$ strings -eS /usr/share/locale-langpack/es/LC_MESSAGES/evince.mo | grep "Document Viewer\|Visor de documentos"
Document Viewer
Document Viewer
GNOME Document Viewer
Visor de documentos
Visor de documentos
Visor de documentos de GNOME
Visor de documentos de GNOME

The problem has been confirmed in Lucid and Maverick.

I attach an screenshot to illustrate the problem.

The same happens in the About dialog box, and also on Fedora 13.


I managed to track down the problem, it's because of this part of shell/main.c:

#if defined(WITH_SMCLIENT) && defined(GDK_WINDOWING_X11)
	egg_set_desktop_file (GNOMEDATADIR "/applications/evince.desktop");
#else
	/* Manually set name and icon */
	g_set_application_name (_("Document Viewer"));
	gtk_window_set_default_icon_name ("evince");
#endif /* WITH_SMCLIENT && GDK_WINDOWING_X11 */

http://git.gnome.org/browse/evince/tree/shell/main.c#n306

The egg_set_desktop_file call does not return the translated value, even that the implementation says so. 

There are two possible solutions: either remove this call entirely, and rely on the direct g_set_application_name and gtk_window_set_default_icon_name calls, or fix the problem in libegg and after that update the copy in evince.
