           Summary: ASSERTION FAILURE in -[WebView becomeFirstResponder]
           Product: WebKit
           Version: 522+ (nightly)
          Platform: Macintosh
               URL: about:blank
        OS/Version: Mac OS X 10.4
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: ddkilzer at webkit.org


* SUMMARY
After bringing the Find dialog up with Command-F, hitting Option-Tab twice
(with a specific preference set) causes an ASSERT_NOT_REACHED() statement to be
hit in debug builds of WebKit.

* STEPS TO REPRODUCE
1. Launch Safari/WebKit.
2. Make sure the "Press Tab to highlight each item on a web page" preference is
checked under the "Advanced" tab in Safari preferences.
3. Hit Command-F to bring up the Find dialog.
4. Hit Option-Tab twice.

* RESULTS
Safari/WebKit crash with an assertion failure in debug builds of WebKit.

* REGRESSION
Only tested with a local debug build of WebKit r24749 with Safari 3 Public Beta
v. 3.0.2 (522.12) on Mac OS X 10.4.10 (8R218).

* NOTES
Console log:

SHOULD NEVER BE REACHED
(/path/to/WebKit/WebKit/WebView/WebView.mm:2396 -[WebView
becomeFirstResponder])
Segmentation fault
