It passes if you run only fast/repaint/background-scaling.html or fast/repaint tests. But crashes always if you run all fast tests. 666809 1 ossy 2012-07-11 09:47:02 -0700 I skipped it on qt-5.0-wk2 to try to paint the bot green. Please unskip it with the proper fix. 718283 2 allan.jensen 2012-09-12 06:05:53 -0700 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. 975501 3 jturcotte 2014-02-03 03:21:38 -0800 === Bulk closing of Qt bugs === If you believe that this bug report is still relevant for a non-Qt port of webkit.org, please re-open it and remove [Qt] from the summary.
