           Summary: Dolphin freezes when connection to a mounted SMB share
                    is lost
           Product: dolphin
           Version: 20.12.2
          Platform: Other
                OS: Linux

SUMMARY

I have a SMB/CIFS share mounted on /mnt/users (with mount -t cifs). When the
samba server is down and the folder dolphin wants to open after being started
is on the share, dolphin will not start.

STEPS TO REPRODUCE
1. Mount a SMB share using mount -t cifs anywhere.
2. Use dolphin to open a folder on the share.
3. Close dolphin
4. Somehow disconnect your device and the SMB server.
5. Open dolphin again

OBSERVED RESULT

Dolphin will create a window and show up in the task bar but in the window
nothing will be rendered. When the connection to the share is lost while
dolphin is showing a folder on the share, it just freezes.


EXPECTED RESULT

Dolphin shows a nice error message and continues to function as normal.
