           Summary: Duplicate Symbol definition warnings .
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit API
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: playmobil at google.com


It looks like some Cocoa calls can load the system copy of WebKit.  For OS X applications that embed their own copy of WebKit, this can lead to errors like the following:

objc[1841]: Class WKAppKitDrawDecoyWindow is implemented in both /Applications/Google Chrome.app/Contents/MacOS/../Versions/5.0.375.38/Google Chrome Framework.framework/Google Chrome Framework and 
/System/Library/Frameworks/WebKit.framework/Versions/A/WebKit. One of the two will be used. Which one is undefined.

Searching for the error appears to show that Chromium isn't the only Mac application suffering from this issue:

Looking at the symbols defined in the WebKitSystemInterface object files, it appears that they contain Objective C classes and categories. Is it safe to have multiple and possibly diverging versions of these loaded into the binary at the same time?
