kmail checks at startup for the localized names of groupware folders on IMAP servers, does not find them and
tries to create untranslated folder names. Those already exist from the previous creation though
and thus the error is displayed every time when kmail starts. Sometimes it even crashs.

Both happens inside kdepim/kmail/kmailicalifaceimpl.cpp

creating the folders uses:
   parentFolder->createFolder( localizedDefaultFolderName( contentsType ) );
which is
  static QString localizedDefaultFolderName( KMail::FolderContentsType type )
  {
    return i18n( s_folderContentsType[type].translatedName );
  }
where translatedName is something like:
  I18N_NOOP( "Mail" )
and thus probably prevents translation?


Folder checking went via:
  findStandardResourceFolder(..)
which uses
  folderParentDir->hasNamedFolder( folderName( itemType, folderLanguage ) );




The dialog was:
KMail found the following groupware folders in shared and needs to perform the following operations:
 * Calendar: no folder found. It will be created.
 * Contacts: no folder found. It will be created.
 * Notes: no folder found. It will be created.
 * Tasks: no folder found. It will be created.

To visualize I added some printfs:
#42#DEBUG# Looking for itemType 7 and folderLanguage 1 and thus folderName=Kalender getting node 0
#42#DEBUG# createFolder Calendar
#42#DEBUG# Looking for itemType 8 and folderLanguage 1 and thus folderName=Aufgaben getting node 0
#42#DEBUG# createFolder Tasks
#42#DEBUG# Looking for itemType 9 and folderLanguage 1 and thus folderName=Journal getting node 0x855db0
#42#DEBUG# Looking for itemType 10 and folderLanguage 1 and thus folderName=Kontakte getting node 0
#42#DEBUG# createFolder Contacts
#42#DEBUG# Looking for itemType 11 and folderLanguage 1 and thus folderName=Notizen getting node 0
#42#DEBUG# createFolder Notes                                               ^^^^^^^
