Description of problem:

This problem happens on Fedora 30, latest kernel, when I use the Gnome Store to remove the Snap-Package of Rambox.

I removed it, since the package seems not to work at all, at least I'm not able to start it, so I'm suspecting SELinux to be the culprit. A friend with who installed Fedora 30 from scratch does not appear to have this problem.
SELinux is preventing snap-update-ns from 'search' accesses on the directory /.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that snap-update-ns should be allowed search access on the  directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'snap-update-ns' --raw | audit2allow -M my-snapupdatens
# semodule -X 300 -i my-snapupdatens.pp
