installation in subfolder -> error 500 with nginx and php5-fpm

[1000i100]

I have a vhost for all my internal use tools (phpmyadmin, roundcube...)
I access them like this :
adminVhost.domaine.com/phpmyadmin/
adminVhost.domaine.com/roundcube/
...
i would like to use rainloop the same way but it look to fail in error 500 when i try to install it in a subfolder (in vhost root, the first screen is displayed well)

Here is my log error message :

2014/01/11 14:26:20 [error] 4380#0: *42 FastCGI sent in stderr: "PHP message: PHP Fatal error:  include(): Cannot redeclare class rainloop\service in /adminVhostFolder/rainloop/rainloop/v/1.6.1.629/app/libraries/MailSo/MailSo.php on line 12" while reading response header from upstream, client: 192.168.1.1, server: adminVhost.domaine.com, request: "GET /rainloop/ HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "adminVhost.domaine.com"

any tips of fix ?

One more thing :
If i change
adminVhost.domaine.com/rainloop/
to
adminVhost.domaine.com/rl/
i have no more a 500 error but this message :
[101] Can't read version file

does rainloop is blacklisted in your app for web file access security ?

[RainLoop]

This is weird. The program has no such restrictions.

Ok, i will make some more test this week, one the same server and on an other.
