df fails on /run/user/1000/doc with "Operation not permitted" #553
Description
Hi,
this is a followup to issue #512 that has become confused by a root/non-root sub-issue. The problem here is that df displays an error message for something that is not an error:
$ df
/bin/df: /run/user/1000/doc: Operation not permitted
Filesystem 1K-blocks Used Available Use% Mounted on
tmpfs 1624464 31012 1593452 2% /run
[...]
Here are xdg-desktop-portal processes that run on this system (note that there are no processes owned by root contrary to the other issue I mentioned):
$ ps aux | grep xdg
bonnaudl 149811 0.0 0.0 80728 6156 ? Ssl 09:44 0:00 /usr/libexec/xdg-document-portal

Here is another relevant process:
root 149819 0.0 0.0 4684 2996 ? Ss 09:44 0:00 fusermount -o rw,nosuid,nodev,fsname=portal,auto_unmount,subtype=portal -- /run/user/1000/doc
Is this problem in xdg-desktop-portal, fuse or df ? I think that at least one of those 3 pieces of software should be modified so that the error message is not displayed.
