it seems that thunar is not able to see the content of the folder where I have mounted the following file systems :
lklfuse -o type=ext4 /dev/ada0s1 /mnt/ada0s1 # CT500 (466 GB / Ubuntu 21.04)
lklfuse -o type=ext4 /dev/ada1p3 /mnt/ada1p3 # Samsung SSD 860 EVO 500GB / nixos
lklfuse -o type=ext4 /dev/da1p1 /mnt/da1p1 # Toshiba (932G)
lklfuse -o type=ext4 /dev/da2s1 /mnt/da2s1 # 1.8T Toshiba
ntfs-3g /dev/nvd0p2 /mnt/nvd0p2 # Windows da 900GB
ntfs-3g /dev/da0p1 /mnt/da0p1 # Elements
ntfs-3g /dev/da3p2 /mnt/da3p2 # 1.8T Seagate
mount -t ufs /dev/ada1p2 /mnt/ada1p2 # Samsung SSD 860 EVO 500GB / FreeBSD da 100 GB
in every case,thunar is not able to display the content of the folders where I have mounted those file systems.Inside them I don't see anything. It seems to me that the bug affects thunar,since I see it using lklfuse,ntfs-3g and even ufs
you can give a look here,where I have explained this problem.
I see the same error even using pcmanfm,caja,nemo...
