Description boospy 2016-04-28 19:58:43 UTC

Hello, 

i've running a Kubuntu 16.04 as client machine. As nfsserver is an Proxmox4.2 (Debian 8 Kernel 4.4). Shares are mounted over FSTAB with ACLoption. So at the most time when i copy ore move a file in or from an ACLplace dolphin crashed with errermessage "Permissions can not be changed PID: 11374 Signal: Segmentation fault" 

But all changes are done. Everything is fine, only dolphin crashed. With Ubuntu 16.04 nautilus an copy over CMD everything goes fine. Strange thing is, when i say:

mount | grep acl 

nothing is going. On an older clientsystem like Ubuntu 14.04 there is this flag. But yes it works over CMD and nautilus, so i thing this is new and normal. 

Reproducible: Always

Steps to Reproduce:
1. add an nfsshare:
/export *(acl,async,no_subtree_check,fsid=0,rw)
/home   *(acl,async,no_subtree_check,rw,no_root_squash)

2. Set the mount in fstab:
nfsserver:/home/       /home/daten_nfsserver/              nfs     rw,_netdev,acl,intr,soft,bg,noauto,x-systemd.automount 0       0

3. copy ore move some files with acl's

Actual Results:  
It copies but dolphin crashes

Expected Results:  
:) not crashing

Also on NFS4.

Thanks for the report. If it's still crashing for you, we need a backtrace with debug symbols and/or a valgrind log. See https://community.kde.org/Dolphin/FAQ/Crashes for details.

It is also on 16.04.3

Comment 5 Elvis Angelaccio 2016-12-27 09:47:04 UTC

Thanks. 

Can you try again with:

valgrind --tool=memcheck --leak-check=yes -v dolphin 2> log.txt

The backtrace does not show anything related to the copy of files. Rather, it shows only XCB stuff, which means you may want to upgrade to Qt 5.6.x

Comment 7 boospy 2017-01-03 20:14:22 UTC

Sorry for the delay. Some things are changed to the first post. Upgraded System with the kubuntu-ppa. Versions are:

KDE Frameworks 5.28.0
Qt 5.6.1 (kompiliert gegen 5.6.1)
Dolphinversion: 4:16.04.3-0ubuntu1~ubuntu16.04~ppa62

The application does not crash anymore, but the errormessage is still existing, and this is blocking an normal officeuser.
But the right ones are applied correctly when copying files. 

Thank you

Thanks for the update.

Comment 9 Julian Steinmann 2018-05-18 16:11:52 UTC

Does the error message still appear with a newer version of Dolphin?

No, it is working fine now on Version 4:18.04.1-0neon+16.04+xenial+build41

Thanks :)
