Unfortunately it isn't so easy to reproduce the bug ...
It passes if you run only fast/repaint/background-scaling.html or
fast/repaint tests. But crashes always if you run all fast tests.

I skipped it on qt-5.0-wk2 to try to paint the bot green.
Please unskip it with the proper fix.

The commit in question changes the lifetime of the Internals structure, combined with the fact it only fails when run together with other tests, it indicates we have a problem with life span of Document and or Internals, which could also explain other bugs with running many tests together fast.
