webview.load_url() segfaults on Linux

[AstraLuma]

Using the gtkwebkit,

#!/usr/bin/env python
import webview
import threading

t = threading.Thread(target=webview.create_window, args=("Test", "about:blank"))
t.start()

webview.load_url("https://www.google.com/")

Produces:

load_html() seems to be ok, though.

There was a threading permission violation. The fix is in master now. If it solved your problem, please close this issue.

Ok, yup. Thank you. Looking forward to the release.
