Comment 2 emohr 2019-11-03 10:36:41 UTC 
Does this crash happen with the current Kdenlive AppImage version 19.08.2b as well?
Comment 3 Isaac A. 2020-01-22 19:17:34 UTC 
I'm seeing this crash as well, I think it could possibly be related to some sort've hardware acceleration as it does not happen in the AppImage, which doesn't support hardware acceleration as far as I can tell.

I'm using an AMD RX 580 on Fedora 31 with Kdenlive 19.12.0.. The AppImage is 19.12.1 so I guess I'll have to wait until the repo updates to test if it's been fixed.
Comment 4 Vincent PINON 2021-02-14 21:51:20 UTC 
Sorry but I can't find meaningful info in the backtrace (nothing related to HW accel neither).
Is it still happening with recent release?
Comment 5 Leon 2021-02-15 05:15:12 UTC 
I tested from my side and could not re-produce a crash anymore. If another can confirm and happy it could be marked as fixed.
