Unfortunately very hard to reproduce bug, most of the time dolphin will hang right after starting in or it might hang if i change to a different directory. I've got multiple nfs mounts but they're all accessible on the console in my places there are also a few sftp links Reproducible: Sometimes Steps to Reproduce: open dolphin or change directories Actual Results: dolphin hangs indefinitely / for a couple of minutes (no high cpu load) Expected Results: no freeze Program received signal SIGTSTP, Stopped (user). 0x00007ffff781091d in nanosleep () from /usr/lib/libc.so.6 (gdb) info threads Id Target Id Frame 3 Thread 0x7fffd9958700 (LWP 5687) "QThread" 0x00007ffff783818d in poll () from /usr/lib/libc.so.6 2 Thread 0x7fffe1fbd700 (LWP 5686) "QXcbEventReader" 0x00007ffff783818d in poll () from /usr/lib/libc.so.6 * 1 Thread 0x7ffff7e20800 (LWP 5682) "dolphin" 0x00007ffff781091d in nanosleep () from /usr/lib/libc.so.6 (gdb) thread apply all bt full Thread 3 (Thread 0x7fffd9958700 (LWP 5687)): #0 0x00007ffff783818d in poll () from /usr/lib/libc.so.6 No symbol table info available. #1 0x00007fffedc0efbc in ??

It occurs on my system too. At every startup, on the first opening of Dolphin. openSUSE Leap 42.1/KDE Plasma 5.5.5
This issue is still existing in Plasma 5.8.3, probably 5.8.4 too! Tested on openSUSE Leap 42.2.
The same issue. I have NFS share. When it was accessed long time - Dolphin staggers. And when NFS share not respond - Dolphin hangs. Here is the screenshot:

Sorry for typos. I'm sleepy. Arch Linux. 2017-09-15. dolphin 17.08.1-1 KDE Plasma desktop 5.10.5-1
Hello, and thanks for reporting this bug! First, please try to reproduce the crash again with the newest version possible (Arch should have 18.04.2). The current backtrace is sadly incomplete, so please install the debug packages needed and upload a new backtrace if you can still reproduce the issue. Thanks again!

This hanging for a while in Dolphin is still existing. (Plasma 5.12 LTS, 17.12.3, openSUSE Leap 15).
Okay, thanks for the confirmation. It'd be great if we could get a full backtrace. Simply install dolphin-debuginfo & generate a new backtrace, then attach it here. Thanks!
Can you please provide a backtrace on the most current version in each of your respective distros. I've not had any crashes at all with Dolphin 20.08.1 so cannot reproduce.

Good that KDE started to close bugs automatically on the certain rules - it is definitely the right practice. For such a severe syndrome bug - 4 people involved - means it is a small rare thing. Especially when I bailed-out I know that NFS/SAMBA handling I wrote here because of - was solved. At least for me Dolphin hung because it synchronously engaged into NFS/SAMBA and waited for downtime, while share was simply offline, I imagine the same is on slow/dodgy connection. But I know that was radically improved in last couple of years, and hanging problem went away for me. IDK if the original bug report relates to network devices - but it was my case which is solved - so I bail-out of the report. Hope you all doing great. I think the bug resolved itself. Or it may be the people have some dodgy `dolphinrc` config file to reset, or some hardware issues, or problem in the other part of the system. Thank you.
