Forgot to mention - the crashing is flaky and the test times out otherwise on all configurations. http://test-results.appspot.com/dashboards/flakiness_dashboard.html#group=%40ToT%20-%20webkit.org&tests=fast%2Fcss%2Fuser-drag-none.html
The crashes are gone, the timeouts persist.
The timeouts are gone after r150334, the test is now failing. http://webkit-test-results.appspot.com/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=fast%2Fcss%2Fuser-drag-none.html http://trac.webkit.org/changeset/150334
There are no references to this bug in any TestExpectations. It's probable this bug was solved at some point but it wasn't marked as closed. I'm closing this bug now. If you think this bug report is still valid, please reopen it and add an entry to TestExpectations.
