Comment 1 Bharadwaj Raju 2023-11-22 14:40:16 UTC 
Can you share the .flatpakref file which caused this?
Comment 2 Patrick Silva 2023-11-22 16:00:49 UTC 
Created attachment 163369 [details]
test file

Cannot reproduce consistently, I need to repeat the provided steps a few times.
Comment 3 Nate Graham 2023-11-27 03:43:19 UTC 
Can reproduce 100% reliably with that file. Backtrace of the crashing thread:
