            Bug ID: 212415
           Summary: WebKit Crashes when SVG Filter Logging is Turned On
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: SVG
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: guowei_yang at apple.com
                CC: zimmermann at kde.org

WebKit crashes when the flag -WebCoreLogging "Filters" is present, which turns on the logging for SVG Filters.
This is due to uncaught null pointers in 

FilterEffect::imageBufferResult(), 
FilterEffect::copyUnmultipliedResult() and 
FilterEffect::copyPremultipliedResult()

Step to reproduce: 
1. Turn on filter logging by adding the flag -WebCoreLogging "Filters" in build scheme
2. Launch MiniBrowser and load an html file with SVG

Result: 
MiniBrowser crashes
