SUMMARY K-Mail crashes by selecting freshly arrived unread Mails STEPS TO REPRODUCE 1. see summary OBSERVED RESULT My email provider is bluewin.ch (Swisscom) an I cannot exclude, That it is not independent of this provider. But it worked with it for several years and the problem started last fall with an update. If a newly arrived mail is selected, the application crashes not allways but in the majority of the cases. If the mail is selectable without crash, it is not deletable or access to any other way of handling, this also leads to a crash. Is the application started again, the mail becomes accessable. Sometimes it needs several restarts. In some cases even the operating system crashes. Old mails are accessible to any handling. SOFTWARE/OS VERSIONS I am using Arch Linux with KDE desktop and the newest version of KDE-Plasma. As I am preparing myself to contribute to KDE, I also have the newest versions of the QT frameworks installed. Linux/KDE Plasma: newest available Version (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: newest Version ADDITIONAL INFORMATION As a retired software developer and lover of Linux/KDE this behavior looks to me like a typical no reference exception, which might be closely linked to the OS. There must have been done some work on this bug allready as it changed its behaviour somewhat, but it got not really fixed.
Please add the backtrace for this crash.
See https://wiki.archlinux.org/index.php/Debug_-_Getting_Traces for more information.

I am using Arch Linux, so i have alwais the newest Version of KDE
How can I change the status? Christophe Giboudeaux has posted what I get sometimes as response from the software. In the majority of the cases however I just get 'A fatal error occured'. Sorry I have not more. Werner
The correct Errormessage that mostly is reportet is: Application: Kontact (kontact), signal: Segmentation fault. The posted one occors i one of about 10 times.
Right now, afte a crash, opening a new mail, I received a new error message. Application: Kontact (kontact), signal: Aborted Using host libthread_db library "/usr/lib/libthread_db.so.1".

Crash is in nouveau_dri.so (Nouveau video driver). If this is reproducible, please report this issue directly to Nouveau developers via https://bugs.freedesktop.org/
Hi The last comment fron Christoph Feck is rather strange. All applicationons rar running fine, just not KMail. This makes it rather difficult to search the error in the driver. I do not understand this comment. good luck W. Bernhard
KMail uses the Chromium web engine (via QtWebEngine) to display mails. This web engine internally uses OpenGL from multiple threads, which the Nouveau OpenGL driver fails to handle. Other KDE applications do not use QtWebEngine.
