Application: kmail (5.4.3) Qt Version: 5.6.2 Frameworks Version: 5.32.0 Operating System: Linux 4.9.56-desktop-1.mga6 i686 Distribution: "Mageia 6" -- Information about the crash: - What I was doing when the application crashed: I attempted to start KMail. Since Plasma is too heavy I run Cinnamon. It is a 32 bit computer without sse2 support. When I attempt to run KMail from a remote computer KMail crashes. When I run it locally the KMail window is just black. The crash can be reproduced every time. -- Backtrace: Application: KMail (kmail), signal: Segmentation fault Using host libthread_db library "/lib/i686/libthread_db.so.1".

The crash is in LLVM called from the swrast OpenGL driver. If this is reproducible, I suggest to report it directly to Mesa developers via https://bugs.freedesktop.org/ Developers there can check if the issue could be due a bug in LLVM.
