huge files created when copying from a network drive.

[Sebastian]

When copying files from a cifs share (mounted via pam_mount) to the same share or to a local drive, sometimes it keeps on copying data and creates a huge files (into the tens of gigabytes). An .goutputstream file is then also created of the same size.

After checking more options. It happens with any filemanager and cp (copying from samba-share to samba-share)

Tested this on ubuntu mate bionic (18.04.2) on amd64

Has corrupted quite some files here now.
