BarManager vs GNU GetText - an invalid pointer operation exception is raised when try to translate the component and then close the application

This issue does not relate to our Suites. The procedure TranslateComponent calls the TranslateStrings method , which does not take the existance of the objects in the list into account, these objects are being destroyed by Assign method calling implicitly.
procedure TGnuGettextInstance.TranslateStrings(sl: TStrings;const TextDomain:string);
var
  line: string;
  i: integer;
  s:TStringList;
begin
  if sl.Count > 0 then begin
    sl.BeginUpdate;
    try
      s:=TStringList.Create;
      try
        s.Assign (sl);
        for i:=0 to s.Count-1 do begin
          line:=s.Strings[i];
          if line<>'' then
            s.Strings[i]:=dgettext(TextDomain,line);
        end;
        sl.Assign(s);
      finally
        FreeAndNil (s);
      end;
    finally
      sl.EndUpdate;
    end;
  end;
end;

As workaround, we suggest that you try to use the following approach:
constructor TForm1.Create(AOwner: TComponent);
var
  I: Integer;
  AObjects: TObjectList;
begin
  inherited;
  AObjects := TObjectList.Create(False);
  try
    for I := 0 to dxBarManager1.Categories.Count - 1 do
    begin
      AObjects.Add(dxBarManager1.Categories.Objects[I]);
      dxBarManager1.Categories.Objects[I] := nil;
    end;
    TranslateComponent(self);
    for I := 0 to AObjects.Count - 1 do
      dxBarManager1.Categories.Objects[I] := AObjects[I];
  finally
    AObjects.Free;
  end;
end;
