Bug#677872: dolphin doesn't work correctly with nfs share

[Pavel Yakunin <pyakunin@gmail.com>]

Package: dolphin
Version: 4:4.7.4-2
Severity: normal

Dear Maintainer,

Seems that the dolphin cannot determine if the nfs share is already mounted. 
I have a nfs share that I can mount as user. When I try to browse it with Dolphin for the first time,
everything is ok: kde mounts it and I can browse the share. But subsequent attempts fail with the "mount.nfs: /mnt/archive is busy or already mounted". 
Neither Dolphin nor plasma device manager applet can unmount the share (the corresponding icons in Dolphin and plasma applet show that the share is 
not mounted while it is actually mounted). The nfs itself is ok, I can mount/umount and browse it without any problem.

In addition, I've found the report about similar behavior in the Arch: https://bbs.archlinux.org/viewtopic.php?id=132561

Here is a part of my fstab:
     liveserv:/mnt/archive/             /mnt/archive/           nfs     noauto,user           0 0

and /proc/mounts
     liveserv:/mnt/archive/ /mnt/archive nfs4 rw,nosuid,nodev,noexec,relatime,vers=4,rsize=262144,wsize=262144,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=192.168.1.102,minorversion=0,local_lock=none,addr=192.168.1.104 0 0

there is a backslash in the proc/mounts, but it makes no difference, I've tried various combinations of slashes.

All the best,
Pavel
