I have double tested this: reverting r171957 fixes this issue.

You can check the diffs here: http://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/r171957%20%281853%29/svg/custom/

Seems that this has also caused (at least) this two new flakiness on GTK:

Unexpected flakiness:
  fast/canvas/canvas-strokeRect-gradient-shadow.html [ Failure Pass ]
  fast/css/table-border-radius-with-box-shadow.html [ ImageOnlyFailure Pass ]

The diffs are:

Also the following test is flaky now:

fast/canvas/canvas-composite-image.html [ Failure Pass ]

Updated the GTK TestExpectations on http://trac.webkit.org/changeset/171963 for this failures
