Bug 501570

Application: kmail (6.3.3 (24.12.3))
 (Compiled from sources)
ApplicationNotResponding [ANR]: false
Qt Version: 6.8.2
Frameworks Version: 6.12.0
Operating System: Linux 6.13.7 x86_64
Windowing System: X11
Distribution: "Gentoo Linux"
DrKonqi: 6.3.3 [KCrashBackend]

-- Information about the crash:
Since a few days, KMail is crashing randomly (at least, that's how it looks like). The last time it happened it was right after pressing the Ctrl+Enter shortcut to send a mail, but it has also crashed while minimized to the system tray, with no open windows (I don't know whether it was checking mail or not at the time).

The crash can be reproduced sometimes.

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