I'm filing this bug after a brief discussion with maintainer on IRC on the topic of nextcloud shipping with a config.php which throws the following error upon accessing index.php:
2017/02/18 23:56:08 [error] 82852#101771: *1 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught Error: Call to a member function getLogger() on null in /usr/local/www/nextcloud/index.php:61
thrown in /usr/local/www/nextcloud/index.php on line 61" while reading response header from upstream, client: 192.168.1.114, server: 192.168.1.53, request: "GET /index.php/ HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "192.168.1.53"
The issue is, however, fixed simply by deleting the included config.php file provided by upstream, which could be done for the port if the file matches the checksum from upstream (so as to avoid any issues with packaging). That way, whenever a user points a httpd to the nextcloud directory, they're presented with the nextcloud installation wizard.
I believe maintainer is already working on a fix, so this bug is just to serve as a reminder/reference for which bug it fixes.

pkg-plist: do not copy sample configuration
If I understand that right:
Currently the port installs a sample configuration file by copying
config/config.sample.php to config/config.php
As you mentioned: that should not be the case (the last Parameter in the
sample even tells us not to do so).
> * This entry is just here to show a warning in case somebody copied the sample
> * configuration. DO NOT ADD THIS SWITCH TO YOUR CONFIGURATION!
> 'copied_sample_config' => true,
but no warning is shown on the website :-(
(You might want to mention this to the maintainer)
See patch on how to stop this the easiest way, I think.
