Description Ole Reier Ulland 2018-01-03 08:01:47 UTC

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".

Comment 1 Christoph Feck 2018-01-17 22:09:03 UTC

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.
