Core: Sync didn't work with Android Caldav

[rehoehle]

We have a problem with a sync of an Android device with CalDav Sync.

Expected behaviour

Calender should sync. Entries are available but doesn't appear on the device.

Server configuration

Operating system:
Ubuntu 16.04

Web server:
Apache 2.4.18

Database:
MySQL 5.7.20

PHP version:
7.0.22

ownCloud version: (see ownCloud admin page)
10.0.4.-1.1 (From repo)

Updated from an older ownCloud or fresh install:
Update from OC 9

Where did you install ownCloud from:
Repository

I've raised the loglevel and debug to a higher level. But there is no error in the logs. Then i tried so fetch the data manually with curl and when i run the following command:

curl -u xxx -X REPORT https://oc.ppcmusic.de/remote.php/dav/calendars/xxx/default/

i get the following error:
```"app":"webdav","method":"REPORT","url":"/remote.php/dav/calendars/xxxx/personal/","message":"Exception:

So i think the entries doesn't appear because there is an parse error. Does anyone have that problem in the past? We have checked the error with a new user and new entries but we can't find any problems.

[ownclouders]

GitMate.io thinks a possibly related issue is #28826: Raised exceptions about REPORT operation when opening comments.

[rehoehle]

Perhaps but that here is a problem regarding the calender. And not the core or comments.

Same bug for me, I fix it with this : https://central.owncloud.org/t/owncloud-10-0-4-caldav-sync-with-cellphone-workaround-needed/10797/3
It will be fix into OC 10.0.5
