Start up the PC.
I have KDE set to remember my apps, so after KDE desktop is visible Dolphin starts.
I left Dolphin pointing to my nfs share
It shows an empty directory, and displays this message:
"An error occurred while accessing ''192.168.1.2:fotos on 192.168.1.2:fotos', the 
system responded: mount.nfs:/media/fotos is busy or already mounted."

I also have a console open. I can list the files in the folder using the command line, so it is mounted ad it works.
Sometimes I get a message notification saying 'No devices available'

After I wait a few minutes, when I press F5 (refresh) in Dolphin the NFS share becomes visible.

I see more problems reported with NFS, but I am not sure if they are the same problem.
I really want to work with you, the developer, to get this bug fixed, since it is a use case
that is so elementary... Just let me know what you need me to do :-)

Reproducible: Always

Steps to Reproduce:
1.start pc
2.open dolphin
3.navigate to an NFS share
Actual Results:  
no files listed, dolphin gives an nfs error message

Expected Results:  
I can see the NFS share
