New crash information added by DrKonqi

kmail (5.3.0 (QtWebEngine)) using Qt 5.7.0

- What I was doing when the application crashed:

I get the same backtrace when deleting a mail from a thread which isn't the first one in the thread. Doesn't happen every time, but almost every time.
Version is 16.08.0/5.3.0

-- Backtrace (Reduced):

That is possible, I had pressed delete on something befoore it crashed (I distinctly remember because it was an accident).
