Endless redirect loop with owncloud 5.0.9 on IIS 7.5

[bertyhell]

I tried installing owncloud 5.0.9 on IIS 7.5
PHP 5.4.17 nts win32 VC9 x86
Windows 7
MySQL 5.6.12
After i got all the configurations correct i was able to enter my username and password
but then i get:
This webpage contains a redirection loop
The webpage at http://localhost:3334/index.php/apps/files lead to to many redirects. This problem can possibly be fixed by clearing your cookies. if not, it might be a problem with the server configuration and not a problem with your computer.
Errorcode: ERR_TOO_MANY_REDIRECTS

clearing the cache didn't help (big suprise ^^)

This look very similar to some of the problems before version 4.0.2
so i tied some of the suggested fixes (\index.php instead of /index.php, ...)
but nothing seems to work.

Anyone got an idea?
How can i help to debug this bug?

"C:\PHP\php.ini"

"C:\inetpub\wwwroot\owncloud\lib\base.php"

Is this still happening?

In case anybody is finding this old issue for his current problem: Could be related to a wrongly configured session path (or a disk full with session data). See also here: #2886 and here: https://forum.owncloud.org/viewtopic.php?f=23&t=15040

Also possibly related to #4895 that is fixed with 5.0.12
