Error while running preview:pre-generate

[GAS85]

Hi All,
just after few seconds after I run
sudo -u www-data php /var/www/nextcloud/occ preview:pre-generate
I had an error:
PHP Fatal error: imagecreatefromjpeg(): gd-jpeg: JPEG library reports unrecoverable error: Unsupported marker type 0xba in /var/www/nextcloud/lib/private/legacy/image.php on line 538

My system is:
PHP 7.0.13
mysql 5.7.17
Nexcloud 11.0.1

nextcloud/server#3393

In my opinion the app should be downgraded to beta state.
Sorry.

This was a server bug. That will be fixed in NC12 (nextcloud/server#3778)
