More than 3 fingers on webview causes app crash?

Question

Like the title says, when I drag more than 2 fingers across my webview. It causes my app to crash with the following log:

Stacktrace from my Desire HD running 4.2.2

I have looked up the error and it looks like the issue of Webview memory leak but I'm not sure. Webview is displaying dynamically generated HTML with some assets in the assets folder such as image/javascript. Any help appreciated! Thanks
