Description

This autotest frequently gives different results on consecutive runs.

For example, from http://testresults.qt-project.org/ci/QtBase_master_Integration/build_02269/win32-msvc2010_Windows_7/log.txt.gz :

The test failed twice in two consecutive runs, but a different testfunction failed each time.
