Stalefiles what does it mean?

I have this Output.

What does it mean?
What must I do with that?

Greetings Sven


It is a message of the "Crash recovery" feature of Kdenlive. There is a bug on some systems that triggers this, see our bugtracker: and

This should now be fixed in latest git, I am waiting for feedback. As a workaround, you can disable the "Crash recovery" feature from Kdenlive's settings dialog.


It is one of the latest Versions..
But it is an old Projekt..


If you are using the sunab expertimental repository, it usually compiles daily, but depending on when the change is made, it can take 1-3 days before that change reaches the sunab package.
