Application: kontact (5.23.1 (23.04.1))

Qt Version: 5.15.9
Frameworks Version: 5.106.0
Operating System: Linux 6.3.2-1-default x86_64
Windowing System: X11
Distribution: openSUSE Tumbleweed
DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
What I did do: write an email and did do a trial to correct the orthography. I did change to the desired language (from Italian (default) I did define German. After which I tried to run also an orthography check from the menu. I defined the list of fallback languages anew. I did save, but then, for circumstances, left Kontact/email composer open idling. By coming back, when activating the system, Kontact segfaulted. This is quite repeatable, although I wouldn't call it "granted" or 100% reproducible with the same assets. However a strong frequency of the issue convinced me to report.

The reporter is unsure if this crash is reproducible.

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