WebKitGTK+ 2.12.4 loads forever when attempting to display a customer's internal page. It's a regression from 2.12.3 and I'm bisecting it on the 2.4 branch now.

When running with a debug build, instead of loading forever, we hit this assertion:

ASSERTION FAILED: !HashTranslator::equal(KeyTraits::emptyValue(), key)

That's not a very good backtrace. I'll try to get a better one, but I have to do it manually as coredumpctl is broken in Fedora  ATM.

Another user is complaining that ubuntu.com loads forever. I couldn't reproduce the issue on that page, though.
