Comment 1 Christoph Feck 2020-07-22 18:08:48 UTC

Version 5.14 is no longer maintained and the Discover code has been improved/changed a lot since then. Additionally, the crash is deep inside Qt code, and your Qt version also isn't up-to-date. I suggest to update Qt at least to a recent 5.12 LTS version, but 5.13, 5.14 and 5.15 have also been released in the meantime.

If you can reproduce this issue with version Plasma 5.18 LTS or 5.19, please add a comment with an updated backtrace.
