Summary: Crash when clearing webkitTransitionDuration in
webkitTransitionEnd event handler
Product: WebKit
Version: 528+ (Nightly build)
Platform: Macintosh
OS/Version: Mac OS X 10.5
Status: UNCONFIRMED
Severity: Normal
Priority: P2
Component: CSS
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: thomas at fesch.at
I've an event handler on document that is fired on 'webkitTransitionEnd'. If I
try to set the affected element style.webkitTransitionDuration property to an
empty string, WebKit nightly crashes.
I'll try to provide a reduced testcase.
Here's the crash log:
