Comment 15 for bug 454297

I observe the same behavior as described above, but it's not limited to images or videos - it also happens with TXT files. Often it's enough to save a file, then rename it and press refresh and either all the files from that folder disappear or nautilus doesn't show the file that has just been renamed.

This bug seems to be a duplicate of more generic bug #383927, where Alastair Carey wrote in comment #19: "now it's very common in Nautilus - any time I move a file that is represented by a thumbnail from one folder to another, Nautilus can't show the entire contents of the destination folder - sometimes Nautilus won't show anything, other times it shows everything but the file just moved. Any file that uses a thumbnail seems to be able to set this off - not just videos, but PDFs, and document files if an OpenOffice thumbnailer extension is installed. Closing and restarting Nautilus doesn't seem enough to reliably fix it."

As to my experience this behavior didn't happen "every time I was moving a file", but it was frequent enough to make me select an option to never create thumbnails for TXT files or any other files that can be previewed with a thumbnail.
