           Summary: [ATK] AX: Hang from atk_text_get_text_at_offset for
                    sentence boundary at final offset
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Accessibility
        AssignedTo: webkit-unassigned at lists.webkit.org

test case

Steps to reproduce:
1. Launch the attached accessible-event listener in a terminal
2. Launch the test case in GtkLauncher or MiniBrowser
3. Resize the browser window so that the text wraps, splitting "text-based" from "setup"
4. Tab to give focus to the link in the test case

Expected results: GtkLauncher/MiniBrowser's WebKit process would not hang.

Actual results: GtkLauncher/MiniBrowser's WebKit process hangs.

Important: If in step 3 you do not have the text split/wrapped as described, there will not be a hang. Changing other aspects of the test case (e.g. the style, removing the final div's text, removing the whitespace in the source before setup) also makes the hang go away. Seems you need just the right combination of things, but when you have them the hang is 100% reliable.
