Qt Version: 5.14.0

-- Information about the crash:
- What I was doing when the application crashed:

i click on a mail then i got the kmail welcome screen instead of contents.

this phenomenon occurs this day for the first time.

then i close kontact
then i start kontact 
then drkonqui warns me that kontact is crashed but kontact gui is there and i can use kmail to see again mail contents

it seems that it is just after receiving a spam in spambox.
i know that some kind of bad built spam cause akoandi does not respond.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
