Thanks for the bug report. I'm sorry we weren't able to get to this yet. There have been many fixes and improvements since this was reported, and this issue may have been fixed. I don't see a segfault running either of the two examples in today's git-master. Can you please re-test on your system with Plasma 6.4.1 or later and let us know if you can still reproduce the problem? If you can, please set this report back to REPORTED. Thanks!
