I am getting the following error when trying to copy a particular file:
'Error splicing file. Input/output error.'
I get this same error from File Manager and from a terminal prompt.

This is being copied to an NTFS partition so might be related to ntfs-3g. Also it is a bit of an obscure file in that the existing file shows as being 127Gb in size but it cannot actually be that big as the whole partition is only 37Gb! It was created by qemu-img converting a VM from hyper-v.
