           Summary: REGRESSION: Assertion failure in scheduleRelayout
                    visiting Bookmarks view while a page is loading
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: NEW
          Keywords: InRadar
          Severity: Normal
          Priority: P1
         Component: Page Loading
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mjs at apple.com


2007-01-30 13:42:44 John Sullivan:
To reproduce:
1. visit bookmarks view
2. double-click some bookmark that's reasonably slow to load
3. after the page appears, but before it's finished loading, click Back button

Assertion fires:

    ASSERT(m_frame->view() == this);

2007-01-30 13:50:04 John Sullivan:
This is easy to reproduce, but doesn't necessarily happen every single time,
possibly just because it depends on the timing of clicking the Back button.

On a release build I often get a crash following these steps, which could be a
downstream symptom of the same problem. That is written up separately as
4964698 in case it is not the same problem.

2007-01-30 20:31:01 Maciej Stachowiak:
I strongly suspect this and 4964698 are the same bug.
