mkdir /home/user/{test1,test2}
ln -s /home/user/test1/ /home/user/test2

If you open the /home/user/test2/test1 in krusader, and then create a new file using an external application, krusader not show the file until you refresh the directory (get out and go back to the directory)

If you open the /home/user/test1 in krusader, and then create a new file using an external application, krusader show the file immediately without refreshing directory.

Dolphin in both case works as expected (show the file immediately without refreshing directory.
)

Reproducible: Always

1. mkdir /home/user/{test1,test2}
2. ln -s /home/user/test1/ /home/user/test2
In krusader
3. Open /home/user/test2/test1
In konsole
4. touch /home/user/test2/test1/file1


Actual Results:  
krusader not show the file until you refresh the directory (get out and go back to the directory)

Expected Results:  
krusader show the file immediately without refreshing directory.
