Description R2Y 2017-10-30 13:13:38 UTC

I have the "segmentation fault" error on my laptop when i changing settings in memory usage widget.
My hardware configuration: https://linux-hardware.org/index.php?probe=dc9faf110a
also u can see the video with this problem: vk.com/video248019601_456239046
I think this is very important bug in plasmashell because I have same errors with weather widget, network monitor widget and some widgets with russian names(I don't know english names of them).

Technical information:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
