Bug#881284: dolphin: Copying to cifs mounted shares is limited to filenames <127 characters

[Leos Pohl <leosenko@gmail.com>]

Package: dolphin
Version: 4:16.08.3-3
Severity: important

Dear Maintainer,


   * What led up to the situation?
Mount SMB share using mount -t cifs //server/share /mnt/dir -o username=someone,password=secret,domain=dom,uid=1000,gid=1000
Attempt to copy with Dolphin a file with filename longer than 126 characters (including extension)
Dolphin responds: Could not write to smb://someone@dom@server/share/verylongfnameverylongfname.part

This is not related to any restrictions in Windows share as cp and Krusader can copy the file without issues.
The file can be copied within local filesystem and through sftp.
