Description Alvise 2011-12-11 15:07:32 UTC

Version:           4.7 (using KDE 4.7.3) 
OS:                Linux

Most KDE application offer a way to switch the language of just a single
application via Help->Switch Application Language. This will make this
particular application ignore system-wide language settings and follow only
these override settings for language strings.

The "switch application language" windows offers also a button enabling to come back to language "Defaults". With the term defaults, we should expect that KDE turns back to the system-wide settings (that are defined in system settings -> Common appearance and behaviour -> Locale -> Country region & language -> Languages.
Instead, the application settings are reset to "American English" independently from the system-wide settings

Reproducible: Always

Steps to Reproduce:
1. Change the language for one application (eg Dolphin) via Help-> Change application language. Validate
2. Switch back the application language to system wide defaults by clicking on Help-> Change application language -> Defaults


Actual Results:  
Come back to Help-> Change application language : the only language set will be "American English"

Expected Results:  
There should be the same languages as defined in system settings -> ... -> locale -> languages

    KConfig: properly implement revertToDefault().
    
    Now it really removes the entry from the local file, instead of copying
    the value from the global file ("defaults" file, in internal terminology).
    This implements a long-standing TODO, which is now removed from the TODO file.
    
    And it doesn't mark the KConfig as dirty if there's no local entry,
    which makes closing kmail composer windows a LOT faster.
