This happens in Qt event loop handling, that’s why there is no reference
to KMail code.

The relevant part of the code looks like:

  void RenderProcessHostImpl::ShutdownRequest() {
    // Notify any contents that the renderer might shut down.
    for (auto& observer : observers_) {
      observer.RenderProcessShutdownRequested(this);
    }
    ...
  }

This means one of the observers is invalid. It may be coming from KMail code.

Adding a Forwarded link to the KDE bug with the same stacktrace.
