           Summary: Assertion reached in FrameView::paintContents()
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jalkut at red-sweater.com


I am debugging my app against trunk WebKit, compiled for arch i386, over the
past few days.

A few times I have run into an assertion firing in FrameView::paintContents, at
line 1685:

ASSERT(!needsLayout());

I don't know if my use of WebKit is unusual, or if this is an assertion that
many people observe in day-to-day debugging. Just wanted to submit it in case I
can help narrow down what is going on here to cause this assertion to fire
irregularly in my usage.
