[António Fernandes <antoniof src gnome org>]

commit 95d35aedf68f0398a6ee9e0b0af9ce80528fdc22

    general: Use parameter type list, even if function takes none
    
    Newer compiler versions (i.e. Clang 15) failed to compile nautilus,
    because the declaration did not match the function definition.
    See: https://reviews.llvm.org/D122895
    
    Fixes #2378
