Comment 1 for bug 1177357

I'm experimenting the best way to test with an existing database in the tests, such as a "data" function (see http://qt-project.org/doc/qt-5.0/qtquick/qml-testcase.html). Unfortunately I'm hitting QML crashes there (the -platform business isn't terribly robust) so not sure yet if this is the best option.

Meanwhile I reproduced unexpected failures by simply using a temporary file instead of in-memory, which may be related.
