- 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
