filepath for comments with image didn't work

Hello,

After submitting comments with the image (Comment Upload module), I've got the following warning:
Parameter 2 to filefield_paths_filefield_paths_process_file() expected to be a reference, value given in */www/***/includes/module.inc on line 482

Path for "Comment Upload Path settings" doesn't work correctly and uses standard sites/default/files/

At the same time, "Workflow settings Upload Path settings" works good.
I've tried to use 6-1.4 and dev version.
