I am quite sure that that it's related to proxying roundcube. I got it
working by moving it outside of the proxy. Since then I don't get the
error message anymore.

What is necessary to setup roundcube behind an Apache proxy? I tried to
get it work with a simple

> # proxy the connection to webmail                                            
> ProxyPass /webmail/                                        
> ProxyPassReverse /webmail/                                 
> ProxyPassReverseCookiePath /webmail/ /                                       

I am not sure about the `ProxyPassReverseCookiePath` setting.

I haven't tried it with nginx yet though. Maybe a simple

> location / {
>     proxy_pass;
>     proxy_set_header Host      $host;
>     proxy_set_header X-Real-IP $remote_addr;
> }

does it. Any experience?
