Hello! Thanks for the very helpful reply. I did indeed find a backup file a few versions back that didn’t have the issue. It’s a good amount of work lost, but it’s a starting point. I see that the backup timeline points to subfiles for each backup, so I’ll include those in the bug report as well.
Yeah, I saw that .kdenlive files were human readable, but I couldn’t see why that particular chain entry was broken, and the error message isn’t particularly informative. I’ll try to diff the first broken backup with its working predecessor and see if there’s anything obvious. And of course, I’ll also file a bug.
Thanks for the help!
