Bug ID: 401829 Summary: KMail crashes every time while closing Product: kmail2 Version: 5.7.3 Platform: Ubuntu Packages OS: Linux Status: REPORTED Keywords: drkonqi Severity: crash Priority: NOR Component: general Assignee: kdepim-b...@kde.org Reporter: kop98...@freemail.hu Target Milestone: --- Application: kmail (5.7.3) Qt Version: 5.9.5 Frameworks Version: 5.44.0 Operating System: Linux 4.15.0-42-generic x86_64 Distribution: Ubuntu 18.04.1 LTS -- Information about the crash: - What I was doing when the application crashed: I closed KMail - Unusual behavior I noticed: Seg Fault. Using QtCurve widget style with transparent app background causes the crash. If I select any other style, KMail exits normally. (Could be related: Double Commander-qt also doing this) The crash can be reproduced every time. -- Backtrace: Application: KMail (kmail), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
