           Summary: A particular animated SVG crashes in filter code
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
               URL: http://www.bjoernsworld.de/temp/eventflow2.svg
        OS/Version: Mac OS X 10.0
            Status: NEW
          Severity: normal
          Priority: P2
         Component: SVG
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: mjs at apple.com


The following SVG will likely be linked from a future w3c specification
document:

http://www.bjoernsworld.de/temp/eventflow2.svg

It would be nice if WebKit didn't crash on it.

It dies from an uncaught ObjC exception apparently:

Exception:  EXC_BAD_ACCESS (0x0001)
Codes:      KERN_INVALID_ADDRESS (0x0001) at 0xbbadbeef
