In tools.py, I have insert the Molecola patch and modify it with "..." to deal 
file's name with SPACEs :
            # Molecola patch
            #ret= _Command._run( [_Command._exiftran,opt,'-i',self.__file] ) # exiftran rotate internal exif thumb
            _Command._run( [_Command._exiftran,opt,self.__file,'-o',self.__file+'__tmp__.JPG'] ) # exiftran rotate internal exif thumb
            os.system('mv -f "%s" "%s"' % (self.__file+'__tmp__.JPG', self.__file))

and 
                # Molecola patch
                #ret= _Command._run( [_Command._exiftran,exiftranOpt,
                #              '-i',self.__file] )
                _Command._run( [_Command._exiftran,exiftranOpt,
                self.__file,'-o',self.__file+'__tmp__.JPG'] )
                os.system('mv -f "%s" "%s"' % (self.__file+'__tmp__.JPG', self.__file))
