I’ve learned this lesson with my Android phone a few years ago. There it was actually about sqlite databases of a system app (contacts I think?), but this can happen with other formats too. Worst is if it doesn’t just error out, but tries to work with “garbage”, because it’ll possibly take much more time to debug it, or even realize that your data is corrupt.
that’s right, but as I remember the error was talking about being unable to launch that KDE-specufic countdown overlay. journalctl has shown such an error for every time I tried to stop the session in any of the ways.
that’s not how I understand the system is working. could you elaborate?
