I have the same problem, but it seems slightly inconsistent.

- It crashes even if the credentials are registered
- I managed to open the SMB without triggering the bug by using the detailed view, listing a subfolder of the share with the arrow left to the share’s name, opening it, then going one folder up.

So it seems it’s clicking on the share’s name in the Network’s special Dolphin page that makes it crash. It also seems entering the URL directly makes it crash at least some of the time.
