Description Andreas Sittinger 2019-11-05 20:11:04 UTC 
Application: dolphin (18.12.3)

Qt Version: 5.9.7
Frameworks Version: 5.55.0
Operating System: Linux 4.12.14-lp151.28.20-default x86_64
Distribution: "openSUSE Leap 15.1"

-- Information about the crash:
- What I was doing when the application crashed:
entered address line as smb://ds411
filled pop-up for user name and password
Dolphin crashes

this particular problem seems to be around for 12 months or more, I have seen it in my configuration for a long time;
it was also found in OpenSuse Leap 42.3, and very likely any older versions I used; same for Ubuntu 18.04.3 LTS (all plain vanilla out of the box)

the server access in general works fine, like using smbclient;
please note this server has 10 shares and a total capacity of 6TB

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Please install debug symbols for KIO and then post another backtrace. Thanks!

New crash information added by DrKonqi

dolphin (18.12.3) using Qt 5.9.7

- What I was doing when the application crashed:
starting fresh after login
entered address line as smb://ds411
filled pop-up for user name and password
Dolphin crashes 

the core dump will not happen if SMB connection has been stablished successfully before by running smbclient

new backtrace with some more kio-*-debuginfo added

Symbols for kio are still missing (you only have symbols for kcoreaddons).
