Description Vojtěch Zeisek 2016-03-03 15:25:05 UTC
Application: kmail (5.1.2)

Qt Version: 5.5.1
Operating System: Linux 4.1.15-8-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
Sometimes, when I start KMail, it shows information it has crashed, but the application is restarted and works normally. Apart of little disturbance on the beginning, it works perfectly.

The crash can be reproduced sometimes.

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

Similar problem here with Kmail 5.2.0 on 64-bit Mgeia-6-sta1 Plasma login.

At first use after login, Kmail starts normally, but if exited then re-started, it immediately exits without a Kmail window appearing.
  But after doing logout/Login, it again starts normally.

Will try to attach the result of an strace on such an occasion.

Same problem (Kmail will not restart after initial Start/Exit) with Kmail 5.2.3 - whose Help/Version shows:

    . KDE Frameworks 5.24
    . Qt 5.6.1
    . xcb windowing system

with 64-bit Mageia-6-RC Plasma login.

Was happening here on Plasma Mageia-6-rc with Kmail 5.4.3 when the nVidia 'nouveau' driver was in use, but not when the proprietary nVidia driver was in  use.

Maurice, are you sure that your current issue is related to the bug that is reported here? According to the original backtrace, the bug doesn't seem to be related to the graphics stack. Would you please compare a backtrace of your current crashes to Vojtěch's backtrace? Can you provide that backtrace, ideally directly inline in the comment instead of an attachment? Thanks in advance
Comment 6 Maurice Batey 2017-04-18 21:00:31 UTC
But I no longer have a 'current issue', Denis!

Since acquiring stable use of the proprietary '340' nvidia driver, I have found Kmail 5.4.3 to be quite steady and reliable.
Comment 7 Denis Kurz 2017-05-19 08:36:32 UTC
Vojtěch, what about you? Did you try to use the nvidia driver instead of nouveau? Did it fix your problem? What is the most recent version of KMail you experienced this with? Did you try even more recent versions where the crash did not happen? Which version of nouveau do you use? Is it possible to try a newer version?
Comment 8 Vojtěch Zeisek 2017-05-26 12:25:07 UTC
I'm now running openSUSE TW with KMail (and respective KF, Plasma, ...) 5.5.1 and I haven't seen this bug for months. I was never really using NVIDIA graphics - on notebook with Intel+NVIDIA I use only the Intel card. Kernel sees the NVIDIA card (BIOS doesn't allow disabling it completely, but it is inactive) and loads nouveau driver (currently 1.0.15), but it is not in real use. So I doubt it has any effect.

Thanks for the update; closing.
