Public bug reported:
The WebKit2GTK 2.14 (and 2.14.1) version of the library (as used in
Yakkety) has introduced a bug which causes the "notify::title" signal to
be called multiple times then it is necessary, posing a problem for
applications that use the document's title as a bridge between
JavaScript and Python.
This issue is not present under 2.12 (as used in Xenial). This bug
affects WebKit2 powered applications such Ubuntu MATE Welcome and
Polychromatic. Downgrading 2.14 to 2.12 in Yakkety results in expected
behaviour.
Attached to this bug report is a Python example that reproduces this
bug, which needs extracting to /tmp as it reads a basic HTML document.
Under 2.12, clicking the "One", "Two", "Three" links prints "One
clicked", "Two clicked", etc in the terminal once, which is the expected
behaviour.
Under 2.14, clicking the links prints "One clicked", but then a
subsequent click on "Two" and "Three" results in "xxx clicked", a null,
then "xxx clicked" again, which indicates a bug when the notify::title
signal is triggered.
