Segfault in embedded Webkit Browser

Since my upgrade to Ubuntu Zesty netbeans began crashing. I think there are multiple reasons, but one is easily reproducible:

- start netbeans
- Ensure "Tools -> Options -> General -> Web Browser" is configured to "Embedded WebKit Browser"
- Open a new internal browser windows: "Windows -> Web -> Browser"

By default this opens the netbeans homepage. When I move the mouse pointer over the window border (in and out), I get an instant segfault.

I retestet with the Oracle JDK and there is no segfault (this is from the working session):
