https://drone.owncloud.com/owncloud/core/36713/9/6 There are no more "deprecation" warnings - that is good. But:

tests/drone/test-phpunit.sh: line 79:    25 Segmentation fault      (core dumped) $phpunit_cmd --configuration phpunit-autotest.xml ${GROUP} --coverage-clover output/coverage/autotest-clover-"${DB_TYPE}".xml

It gets nearly half-way through the unit tests and crashes. So I don't get to see what the errors actually are - just lots of tests that have "E".
