How reproducible:

Steps to Reproduce:

Working:

$ gio mount -u "smb://bar@SERVER/foo/"
$ gio mount "smb://bar@SERVER/foo/"
$ date | gio save /run/user/1000/gvfs/smb-share:server=SERVER\,share=foo\,user=bar/folder/test.txt
$ echo $?
0
$ cat /run/user/1000/gvfs/smb-share:server=SERVER\,share=foo\,user=bar/folder/test.txt
Thu Sep 15 03:49:57 PM -05 2022

Not working (Permission denied):

$ gio mount -u "smb://bar@SERVER/foo/"
$ gio mount "smb://bar@SERVER/foo/"
$ date | tee /run/user/1000/gvfs/smb-share\:server\=SERVER\,share\=foo\,user\=bar/folder/another-test.txt
tee: '/run/user/1000/gvfs/smb-share:server=192.168.44.1,share=backups,user=bar/folder/another-test.txt': Permission denied
Thu Sep 15 03:55:20 PM -05 2022
$ echo $?
1
$ date | tee /run/user/1000/gvfs/smb-share\:server\=SERVER\,share\=foo\,user\=bar/folder/test.txt (the file exists because it was created above with "gio save")
$ echo $?
0


Actual results:

$ date | gio save /run/user/1000/gvfs/smb-share:server=SERVER\,share=foo\,user=bar/folder/test.txt  (OK)

$ date | tee /run/user/1000/gvfs/smb-share\:server\=SERVER\,share\=foo\,user\=bar/folder/another-test.txt  (Fail: Permission denied)


Expected results:

$ date | tee /run/user/1000/gvfs/smb-share\:server\=SERVER\,share\=foo\,user\=bar/folder/another-test.txt  (OK)
