            Bug ID: 356791
           Summary: KDE Applications won't show contents of nfs mount
                    (automount)
           Product: frameworks-kio
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: fa...@kde.org
          Reporter: i...@kobaltwit.be
                CC: kdelibs-b...@kde.org

KDE gui applications such as Dolphin or kde gui componenents such as the File
Open dialog fail to show the contents of some automounted nfs partitions.

I have attached a screenshot to illustrate the issue. I have captured 4
different applications attempting to display the contents of
/kobaltnet/goudsmid/bin
/kobaltnet is the base mount point for my autofs mounted nfs shares. goudsmid
is one such share.

1. In the top-left you see Konsole running a bash session. It can list the
contents of the directory just fine
2. Top-right is dolphin, which just shows an empty directory
3. Bottom-left is nautilus, which shows the directory contents just fine
4. Bottom-right is the file-open dialog for okular, listing an empty directory

Version-Release number of selected component (if applicable):
I'm not sure I chose the right component. I don't really know which part of
kde/plasma is responsible for this.
Anyway, I see this with 5.4.1-3 and up (also the updates in updates-testing).

There are a few remarkable details that are important:
- this only happens with nfs shares I'm not the owner of (my id is janssege in
the screenshot, the nfs share is owned by user goudsmid). When I access shares
I do own, this behaviour doesn't show.
- the behaviour starts from the second level down the mount point. In the
example, I can see the contents of /kobaltnet/goudsmid, but not of any of its
subdirectories.
- hitting F5 on the empty contents does shortly reveal the contents (it flashes
a fraction of a second) and the the window goes blank again. So this suggests
the directory contents is properly written but then discarded from some reason.

Reproducible: Always

Steps to Reproduce:
1. Set up an nfs share which is automounted, not owned by you, but with proper
group access permissions
2. Open dolphin and navigate to the mounted share. The contents will be
visible.
3. Continue to navigate to a subdirectory.
4. Hit F5

Actual Results:  
3. The contents of the subdirectory won't be shown
4. The actual contents briefly flashes in the window, but won't show
permanently.


Expected Results:  
Normal navigation through the share and all of it's subdirectories. The other
applications (konsole/bash and nautilus) illustrate there's no access/file
permission issue causing this.

This change is fairly recent. I know I recently updated to plasma 5.4.1 from
5.3.x. However the KDE frameworks were also recently updated, so perhaps that's
the culprit.
