v1.6.6.1 -- include-regex path error

v1.6.6.1
Debian 12
It seems the --include-regex in combination with a wildcard path no longer works.
`maldet(1338942): {scan} scan returned empty file list; check that path exists and contains files in scope of configuration.`
e.g.
`maldet --include-regex ".*.php$" -a /backup/home/users/?/www`

restored to v1.6.5 works

hm, maybe an signatures issue?
