Core dump file size is 36 MB and was rejected to upload here. Was uploaded to http://www.mediafire.com/file/6exgsg53mz7sr8z/core.plasmashell.1000.892b6f66b893474bb05bce0a5071c114.854.1605071270000000.zst/file It happens again:
I fulfilled bug ticket, closed or minimized window one after one,
selected 1 folder on the desktop,
pressed Ctrl+X and immediately got a new crash look the same as previous:
`journalctl`:
```

You don't need to provide the full core, just a backtrace of the crash using gdb. Can you do that? What is the guide how to do this? https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports If you have a core file, you can run `gdb /usr/bin/plasmashell /path/to/core/file` and type `bt` and it will display a more readable backtrace. backtrace from 36 MB-file: backtrace was manually edited: neighboring lines of `warning: Can't open file anon_inode:i915.gem which was expanded to anon_inode:i915.gem during file-backed mapping note processing` was replaced into that single line ``` Reading symbols from /usr/bin/plasmashell...

SUMMARY It is hard to reproduce. What I've done right before crash STEPS TO REPRODUCE 1. Was created and deleted about 5 sticky notes widgets on the desktop. Their notifications about to restore them were present on the screen. 2. I create new folder with customized name 3. select 3 files via rectangular selection with mouse 4. Pressed Ctrl+X. Got crash immediately. Desktop panels and desktop icons was auto-restored during a few seconds. After the crash got about 5 sticky notes present on the desktop. Re-delete them, select that 3 files again, cut and paste into the folder with success.
