Application: dolphin (20.12.3)

Qt Version: 5.15.2
Frameworks Version: 5.80.0
Operating System: Linux 5.11.0-40-generic x86_64
Windowing System: X11
Drkonqi Version: 5.21.4
Distribution: Ubuntu 21.04

-- Information about the crash:
- What I was doing when the application crashed:

I navigated through the path in dolphin via smb://, to a spot in which a directory needed to be created, and a file copied. I used the context menu to create the directory, and name it. After I hit "enter" to complete the entry of the directory name, Dolphin crashed. This has happened multiple times. When I restarted Dolphin and returned to the path, the directory I attempted to create did exist. So, Dolphin created it successfully, but then crashed.

- Unusual behavior I noticed:

This only seems to affect network locations accessed via smb://.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
