           Summary: Undeterministic failures in individual (SVG?) layout
                    tests
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P2
         Component: SVG
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: kimmo.t.kinnunen at nokia.com


Some layout tests fail when run individually. Usually the failure occurs for
the first test case run. The failures are SVGTextElement being too wide or
narrow, while rest of the expected output stays same. I'm guessing this bug to
SVG component, nothing certain.

Test cases affected include at least:
svg/W3C-SVG-1.1/styling-css-01-b.svg
svg/W3C-SVG-1.1/styling-css-02-b.svg
svg/W3C-SVG-1.1/styling-css-03-b.svg
dom/svg/level3/xpath/Attribute_Nodes.svg

To reproduce run following runs:

run-webkit-tests svg/W3C-SVG-1.1/styling-css-0{2,1,3}-b.svg
output:
Testing 3 test cases.
svg/W3C-SVG-1.1 .
svg/W3C-SVG-1.1/styling-css-02-b.svg -> failed
..


run-webkit-tests svg/W3C-SVG-1.1/styling-css-0{1,3,2}-b.svg
output:
Testing 3 test cases.
svg/W3C-SVG-1.1 .
svg/W3C-SVG-1.1/styling-css-01-b.svg -> failed
..

run-webkit-tests svg/W3C-SVG-1.1/styling-css-01-b.svg
dom/svg/level3/xpath/Attribute_Nodes.svg
svg/W3C-SVG-1.1/styling-css-0{3,2}-b.svg
output:
svg/W3C-SVG-1.1 .
svg/W3C-SVG-1.1/styling-css-01-b.svg -> failed
dom/svg/level3/xpath .
dom/svg/level3/xpath/Attribute_Nodes.svg -> failed
svg/W3C-SVG-1.1 .
svg/W3C-SVG-1.1/styling-css-03-b.svg -> failed
.


The diffs are always similar to this:
