Issue with Owncloud 10.0.2 and PHP 7.2 on Arch Linux

After updating Arch Linux (and PHP to 7.2), Owncloud don't work anymore.

I get the login mask, but after logging in there is only a:

This page isn’t working

The last message in the owncloud.log is

... "app":"PHP","message":"Declaration of OC\\Files\\Storage\\Local::copyFromStorage(OCP\\Files\\Storage $sourceStorage, $sourceInternalPath, $targetInternalPath) must be compatible with OC\\Files\\Storage\\Common::copyFromStorage(OCP\\Files\\Storage $sourceStorage, $sourceInternalPath, $targetInternalPath, $preserveMtime = false) at \/usr\/share\/webapps\/owncloud\/lib\/private\/Files\/Storage\/Local.php#42","level":3,"time":"2017-12-16T18:24:13+00:00","method":"POST","url":"\/owncloud\/index.php\/login","user":"maxmoon"}

Is there any chance to fix it before the PHP 7.2 support rolls out?

Thanks a lot for your help

ownCloud doesn't support PHP 7.2 yet (just use the search here, at the documentation or at github).
