Thank you for the bug report. Are you sure of the spelling of the symbol name, 'grub_file_ filters' ? There is no symbol by this name anywhere in the grub source code. Have you previously done anything to the bootloader on your system that would have involved installing an out-of-tree grub module built from source?
