The fast/table/multiple-captions-crash3.html layout test is flaky on GTK+. (sometimes, it fails) When it fails the diff is the following: https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/r182796%20%287688%29/fast/table/multiple-captions-crash3-diffs.html
The test(s) filed under this bug have been consistently passing for the last 4000 revisions. Marking bug as fixed. Committed r263254: <https://trac.webkit.org/changeset/263254>
