Bug 471834

Application: kmail (5.22.3 (22.12.3))
 (Compiled from sources)
Qt Version: 5.15.9
Frameworks Version: 5.106.0
Operating System: Linux 6.1.31-gentoo-b x86_64
Windowing System: X11
Distribution: "Gentoo Linux"
DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
I was trying to send an email. Because it didn't go (grayed out) and nothing happened, I closed and restarting KMail, which then crashed.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
