Bug 448024

Application: kmail (5.18.3 (21.08.3))
 (Compiled from sources)
Qt Version: 5.15.2
Frameworks Version: 5.88.0
Operating System: Linux 5.15.12-gentoo-a x86_64
Windowing System: X11
Distribution: Gentoo/Linux
DrKonqi: 5.23.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I had just configures a tag and marked one message with that tag. Then KMail started blocking. (Unending trying-to-open message view.) Then I closed KMail, which causes the crash.

The reporter is unsure if this crash is reproducible.

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