Removing some tests from tst_datepicker.qml can get rid of the segfault. But it seems like random which tests need to be removed. Even removing a single totally unrelated line of code can cause the segfault to appear/disappear.
So, with this tst_datepicker.qml http://paste.ubuntu.com/15684437/ I get these results: tim@tim-mbp:~/dev/ubuntu-ui-toolkit/m/datepicker-segfault/tests/unit_x11/tst_components$ ../../unit/runtest.sh tst_components tst_datepicker.qml Executing dbus-test-runner --task gdb -p --quiet -n tst_datepicker.qml -m 300 -p --batch -p -ex -p 'set print thread-events off' -p -ex -p run -p -ex -p bt -p --return-child-result -p --args -p /home/tim/dev/ubuntu-ui-toolkit/m/datepicker-segfault/tests/unit_x11/tst_components/tst_components -p -input -p tst_datepicker.qml -p -maxwarnings -p 100 -p -o -p /home/tim/dev/ubuntu-ui-toolkit/m/datepicker-segfault/tests/test_tst_datepicker.qml.xml,xunitxml -p -o -p -,txt Working directory: /home/tim/dev/ubuntu-ui-toolkit/m/datepicker-segfault/tests/unit_x11/tst_components DBus daemon: unix:abstract=/tmp/dbus-yBhHzh27Dd,guid=4b8c2f760af281cfdce396a7570780bd tst_datepicker.qml: Started with PID: 28887 Undefined command: "".
