gvfs-open --help prints following text and fails

This tool has been deprecated, use 'gio open' instead.
See 'gio help open' for more info.

/usr/bin/gvfs-open: 10: [: --help: unexpected operator
/usr/bin/gvfs-open: 10: [: --help: unexpected operator
gio: Unknown option --help

Usage:
  gio open LOCATION...

Open files with the default application that
is registered to handle files of this type.

Reason:
gvfs-open uses wrong comparison operator.
command '[' compares strings using single '=' character.
'/usr/bin/[' and bash builtin [ also allow '==', but dash (which currently used as /bin/sh) requires '='.
