Kopia does not start if closed without disconnecting from repo

[justanothergithubuserNr2]

1. Install Kopia from Flathub.
2. Start Kopia.
3. Connect to local drive repo.
4. Do some backup task.
5. Close Kopia.
6. Try to start it again: it does not start anymore.

This can be solved temporarily by deleting ~/.var/app/io.kopia.KopiaUI

To prevent this issue (workaround - no real solution):

1. Start Kopia.
2. Connect to local drive repo.
3. Do some backup task.
4. WORKAROUND: Disconnect from repo.
5. Close Kopia.
6. Try to start it again: it does start.

Currently, the issue cannot be prevented with the 4. WORKAROUND presented before.

I have to delete ~/.var/app/io.kopia.KopiaUI before every start of the app.

I need to find some time debugging this.

I guess a first thing to do would be to start the Kopia flatpak via console to get some debug message: flatpak run io.kopia.KopiaUI

When you "close" the app and the command does not finish automatically, this might be a starting point for investigation. The behavior could be compared to running the Kopia executable outside of Flatpak.

Indeed, the process did not close if I start it vie console:

$ flatpak run io.kopia.KopiaUI

For testing it, it have connected to a test repo and then closed the app.

I checked it and it in my setup the process finished cleanly after closing the app. The log output is:

$ flatpak run io.kopia.KopiaUI

EDIT: Whan I interact with my repo, I also get the certificate errors but it still finishes the process correctly. I don't get the failed to load errors though.

So this doesn't seem to be a Flatpak specific problem. Please report it upstream at https://github.com/kopia/kopia/issues.
