Description Linder 2016-09-09 18:40:10 UTC 
Application: kmail (5.3.0 (QtWebEngine))

Qt Version: 5.6.1
Frameworks Version: 5.25.0
Operating System: Linux 4.7.2-2-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
There is no special action, that causes kmail to crash. Sometimes it crashed directly after starting; sometimes you can view some mails before it crashes. 
The error occures since some days. So I assume, that is has to do with one of the recent updates in SuSE Tumbleweed.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Mark Draheim 2016-09-10 21:29:43 UTC 
probably dup of #368371
Comment 2 Linder 2016-09-24 08:01:28 UTC 
Error is still existing in kmail after last updates of SuSE tumbleweed (now using kernel 4.7.4-1default). kmail is still reporting version 5.3.0.

Crash report looks quite similar to me, but for helping tracking the bug I have attached it below again:

Application: KMail (kmail), signal: Segmentation fault

Comment 3 Gerry Gavigan 2016-10-05 22:08:52 UTC 
Similar problem using kmail5 16.08.1 from openSUSE Tumbleweed 20161003 on a two user system

The underlying mail system seems to be working, e.g., mail is retrieved from the POP3 server and occasionally it is possible to send and receive one email but kmail persistently crashes on both accounts, usually immediately

The crash report couldn't generate anything useful

Running kmail from command line produces this:

Comment 4 Gerry Gavigan 2016-10-06 17:02:30 UTC 
My problem turned out to caused by either the nouveau video driver or a underlying library (libqt5-webengine 5.7.0-4.1) getting uphappy with HTML formatted emails. 

Kmail was an innocent bystander confirmed by replacing nouveau with the nvidia driver.
Comment 5 Wolfgang Bauer 2016-10-08 17:03:04 UTC 
It is a bug in nouveau, nouveau doesn't like multi-threading, see also bug#369514.
Comment 6 Christoph Feck 2016-10-23 02:32:15 UTC 
Crash is in nouveau drivers. Please report this issue directly to nouveau developers via https://bugs.freedesktop.org/
