[Owncloud] All DAV functions seem broken in latest git pull

[Bugzy Little]

Dear Owncloud devs,
   After pulling the latest git version of OC, caldav, carddav, and
webdav stopped working on the following clients:

Thunderbird 12.01 on Win XP  -- caldav
Kontact (KDE 4.8.2 on Fedora 16)  -- caldav and carddav
Dolphin (KDE 4.8.2 on Fedora 16) -- webdav
map network drive WinXP -- webdav

Please note that this problem seems to be different from the issue
that occurred a few days ago which was corrected with the .htaccess
redirect. I tried all the following dav url string patterns:

/remote/*dav.php/
/remote.php/*dav/
(where * = cal, card, and web respectively)

/apps/calendar/caldav.php
/apps/contacts/carddav.php
/apps/files/webdav.php

Accessing any of these urls from the web works and directory
structures as well as *.ics and *.vcf items can be viewed. However,
trying to use the urls in any of the clients mentioned above results
in failure

webdav on windows says : error path is not a valid directory
webdav in dolphin says : folder does not exist

I see the following errors in the apache owncloud log:

[Wed May 09 20:32:23 2012] [error] [client xxx.xxx.xxx.xxx] PHP
Notice:  Undefined index: PATH_INFO in
/var/www/html/owncloud/remote.php on line 5
[Wed May 09 20:32:23 2012] [error] [client xxx.xxx.xxx.xxx] PHP
Warning:  strpos(): Offset not contained in string in
/var/www/html/owncloud/remote.php on line 6

I am not sure that this is a bugs.owncloud.org issue since it is not a
release. However, I can open a ticket for it if you wish.

Thanks,
Bugzy.
