Bug 461360

Application: kontact (5.19.2 (21.12.2))

Qt Version: 5.15.2
Frameworks Version: 5.96.0
Operating System: Linux 6.0.5-100.fc35.x86_64 x86_64
Windowing System: X11
Distribution: "Fedora release 35 (Thirty Five)"
DrKonqi: 5.25.4 [KCrashBackend]

-- Information about the crash:
Im logged in to my linux environment via openvpn and vncserver.  I started viewing my email normally using kontact.  I saw an email that needed my attention by the end of the day; so I then right-clicked on the message to mark it as an action item ... no issues.  But then I thought it would be cool to add a note to the message.  So I performed another right-click, selected 'Add Note', and populated the private note field.  Once finished, I selected OK and then the application CRASHED!
It is highly repeatable as I tried to walk through the steps on this report and it crashed every time.

The reporter is unsure if this crash is reproducible.

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