Summary: [Qt] setDefersLoading crashes very often
Product: WebKit
Version: 528+ (Nightly build)
Platform: PC
OS/Version: Mac OS X 10.5
Status: NEW
Keywords: Qt
Severity: Normal
Priority: P2
Component: Page Loading
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: yael.aharon at nokia.com
In the last few days I hit this crash many times by either showing an alert dialog during load, or by setting breakpoints in the Inspector. The callstack in those cases is very similar. This callstack is from showing an alert during load.
