SUMMARY
In Dolphin when I try to copy or move files into an SMB share I get an error message: "Access denied. Writing to <server address> not possible"

However, creating a text document via the context menu and using any other file browser or using bash scripts to access the SMB share works flawleslly. So it's not a misconfiguration on my SMB server, it's literally Dolphin that's buggy.

STEPS TO REPRODUCE
1. Have a SMB server (I used Samba)
2. Access the SMB address with Dolphin
3. Try to move or copy a file from the local machine to the SMB server

OBSERVED RESULT
Dolphin will say "Access denied. Writing to <server address> not possible" while any other method of writing files to the SMB server works with no issues.


EXPECTED RESULT
Dolphin should be able to write files to the SMB server too............ obviously.
