Application: kmail (5.11.3) Qt Version: 5.12.5 Frameworks Version: 5.60.0 Operating System: Linux 4.19.86-gentoo x86_64 Distribution (Platform): Gentoo Packages -- Information about the crash: - What I was doing when the application crashed: I had just restarted KMail. This was right after I closed KMail because it was stuck syncing a very large IMAP folder (at 99%, high cpu, but not doing anything really, apparently). The crash can be reproduced every time. -- Backtrace: Application: KMail (kmail), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
