Bug 125761 – page crashes WebKit: ARGUMENT BAD in AccessibilityMenuListPopup::didUpdateActiveOption

• Status: RESOLVED
• Resolution: FIXED
• Component: WebCore JavaScript

[Adam Dingle]

I'm running WebKit 2.3.2 in Epiphany built from git master on Ubuntu 14.04.

Every time I visit this page, WebKitWebProcess crashes:

The top of the stack trace looks like this:

I tried visiting this page with WebKitGTK built from svn trunk with debugging enabled.  WebKit failed with this stack trace:

I am not getting this crash while checking on the latest webkit..
The link http://www.gaisma.com/en/location/somerville-massachusetts.html is getting loaded and working well.

Can you please reverify this ..
Thanks

[Adam Dingle]

I can no longer reproduce this either - marking as fixed.  Thanks!
