I think I caused some confusion here. I don't think it's related to gvfs 
because it is mounted via fstab and I'm not using smb:// in location 
bar, so it's mounted like a local filesystem - via mount command. What I 
was speculating about was whether you use gvfs for the local filesystem, 
too, perhaps for caching information, so then this could be an issue. 
When I type ls in terminal, it shows the correct size, but in thunar 
information is not updated correctly until I restart it.

In fact, I can do so, and I can even provide a test case for this. 
Sometimes the old thumbnail will be used, as if the change had not been 
detected. I thought about proposing thunar should reload the folder 
automatically after a custom action has been performed. Unfortunately, 
it seems reloading the folder does not really reload anything here. 
Additionally, this won't fix reloading when someone changes the file in 
a terminal.

Does not tumbler have its own caching mechanism too? Maybe then tumbler 
is at fault, not thunar? How could I test this, or how could one force 
tumbler to regenerate its cache?

(I think I'm getting off-topic now, sorry for that.)
