Description rainer 2016-09-06 11:22:37 UTC 
Application: kontact (5.3.0 (QtWebEngine))

Qt Version: 5.6.1
Frameworks Version: 5.25.0
Operating System: Linux 4.7.2-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
I started Kontact with LIBGL_ALWAYS_SOFTWARE=1, as other reports suggested that in order to prevent crashes in conjunction with the noveau driver I also use. I was browsing my mail folders for unread mail to check it. Having already selected and read a number of items in the reading pane, Kontact crashed when selecting another one.

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

Email document that triggers the crash

I've attached an email which provokes the crash on my system reliably, stripped down from the original "bad" mail by removing all personal information of the original sender.
Comment 5 Justin Zobel 2020-12-17 05:30:08 UTC 
Thank you for the crash report.

Comment 7 Andreas Mahel 2021-01-01 20:46:57 UTC 
Hi Justin,
thanks for checking back.
Yes, I can confirm that the bug still exists. It does not happen as often as it did in the past (only about one out of three login sessions show the issue  as opposed to about 4 out of 5 in earlier days), but it definitely is still around.

Besides that: happy new year :-)
/Andreas
