Summary: Segmentation fault when click and drag mulitple time
in a short time delay
Classification: Unclassified
Product: WebKit
Version: 528+ (Nightly build)
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: WebKit2

Hello,
With a empty html page, it's possible to crash the webkit2gtk engine by clicking and drag multiple in a very short timespan.
Indeed, the WebKitProcess will dead, and the current page will be a blank page. After this behavior, some JS code will not work correctly (a new process webKitProcess is started after few stimulis).
I will have a look closer to this bug.
Platform : Arch linux
Call stack :
Program received signal SIGSEGV, Segmentation fault.
