Comment 10 for bug 2006110

Since it's a race condition, it's hard to reproduce. The most reliable way to do so is with Flatpak 1.14.x, which isn't part of Jammy.
So, if you're fine with having this potential issue for other tools in the OS, that apparently isn't triggered by anything currently in Jammy, then this doesn't need to be addressed.

The more important immediate issue is the one in appstream-glib, and that's being fixed :-)
