Message that caused problem

When KMail attempts to load an autosaved email draft that contains external
image links (e.g., in HTML content) which are no longer accessible (e.g.,
return HTTP 404 Not
  Found or 400 Bad Request), KMail hangs indefinitely on startup, consumes
significant CPU resources, and does not display its main window.


STEPS TO REPRODUCE
1. Stop kmail
2. Put attached file to .local/share/kmail2/autosave
3. Start kmail

OBSERVED RESULT
kmail doesn't open main window
