      Description

      With the introduction of the new platform plugin in Qt 5.3, the QBackingStore autotest started crashing.

      It asserts when the test tries to create a new QBackingStore for its custom Window class (first line in QAndroidPlatformBackingStore ctor).

      Here's the stack trace:

      Here's the output from the test:
