Bug 496170

Application: kmail (6.2.1 (24.08.1))
 (Compiled from sources)
Qt Version: 6.7.3
Frameworks Version: 6.7.0
Operating System: Linux 6.6.52-gentoo x86_64
Windowing System: X11
Distribution: "Gentoo Linux"
DrKonqi: 6.1.5 [KCrashBackend]

-- Information about the crash:
kmail crashes on startup - what else to say other than that this is already reported, I wanted to add backtrace from newer version, but DrKonqi obviously lost the function to find the duplicate, cool ... :-/

The crash can be reproduced sometimes.

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