@pujithadimuthu apologies but I need to ask for some more info for a developer on IRC (#openmandriva-cooker). Could you install the new package ‘plasma-workspace-debuginfo’ from this repo:

http://abf-downloads.openmandriva.org/3.0/repository/x86_64/debug_main/updates/

and be sure your system is otherwise up to date and then run the gdb on most recent plasmashell crash and run ‘bt’ like you did in your most recent post but with the new packages. Sorry about all this but I’m trying to be a “middle man”. If you wish do interact directly with that developer it is @fedya currently he’s using fdrt as handle @ #openmandriva-cooker. I can assure @fedya is very much more knowledgeable than I am.

Edit: @pujithadimuthu after updating your system you should have these or most of these packages in version 5.10.5-3:

lib64kworkspace5_5-5.10.5-3-omv2015.0.x86_64.rpm   03-May-2018 19:02               30295
lib64plasma-geolocation-interface5-5.10.5-3-omv..> 03-May-2018 19:02               10455
lib64plasma-workspace-devel-5.10.5-3-omv2015.0...> 03-May-2018 19:02               34063
lib64taskmanager6-5.10.5-3-omv2015.0.x86_64.rpm    03-May-2018 19:02              103663
lib64weather_ion7-5.10.5-3-omv2015.0.x86_64.rpm    03-May-2018 19:02                9459
plasma-workspace-5.10.5-3-omv2015.0.x86_64.rpm     03-May-2018 19:02             6902515
sddm-theme-breeze-5.10.5-3-omv2015.0.x86_64.rpm    03-May-2018 19:02              185591

I have all except ‘lib64plasma-workspace-devel’ which won’t install because “The following packages can’t be installed because they depend on packages that are older than the installed ones”. And no I’m not sure why we need some of them, I just followed @fedya’s instructions.

Looks like you have ‘plasma-workspace-debuginfo’ and associated packages. So now just need to run on most recent core dump of /usr/bin/plasmashell:

# coredumpctl gdb XXXX
...

So we can’t get a useful backtrace. @Colin suggested that maybe you would get a backtrace if you installed nVidia proprietary driver? That is up to you.

Also have you tried this? This is only useful if you don’t use samba. But even if you do it may be something to try to help find cause of issue.
