Comment 1 alancio 2020-02-20 16:08:23 UTC

I can reproduce this crash consistently by following these steps:

1. run kate
2. write anything on new buffer
3. ctrl+w

I hope it can be solved soon, I tend to use keyboard shortcuts a lot.

Comment 2 Christoph Feck 2020-02-27 13:11:38 UTC

What distribution is this? Something is broken with libcanberra or libasound setup, or with the dynamic library loader.
