Warning: Call-time pass-by-reference

Hi there,

I get the following php waring once I enable apachesolr_multilingual_textfile module:

Warning: Call-time pass-by-reference has been deprecated in [path_to_modules]apachesolr_multilingual/apachesolr_multilingual_textfile/apachesolr_multilingual_textfile.module on line 123

Warning: Call-time pass-by-reference has been deprecated in [path_to_modules]apachesolr_multilingual/apachesolr_multilingual_textfile/apachesolr_multilingual_textfile.module on line 128

I know I can suppress the warning by setting allow_call_time_pass_reference to true in php.ini. But could this be fixed?
Thanks.isn't there
