           Summary: Uninitialized variable in -[WebDefaultPolicyDelegate

                    stener:]
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.

-[WebDefaultPolicyDelegate
webView:decidePolicyForMIMEType:request:frame:decisionListener:]

has the following code in its implementation:

    if ([[request URL] isFileURL]) {
        BOOL isDirectory;
        [[NSFileManager defaultManager] fileExistsAtPath:[[request URL] path]
isDirectory:&isDirectory];

        if (isDirectory) {
            [listener ignore];


isDirectory is only filled in by the NSFileManager method in the case that the
file exists. In all other cases we are using an uninitialized variable.
Initializing the variable is sufficient to solve the problem.
