Bug description

I can't copy/move files/folder witch shared with me and others (NC 25.0.4).

Steps to reproduce

example scenario:

• Folder1 shared with group1 (include user1 and user2 without resharing access) by admin1.
• Folder1 contains subFolder1.
• subFolder1 contains FileA.
• when user1 try to copy/move FileA from subFolder1 to Folder1, raised an error: could not copy.
  if try for a second time, raised an error: could not copy, the file exists.
  If you check Folder1, you can find FileA and when you downloaded that, the file crashed.

Expected behavior

file/folder copy/move correctly.

Start by reproducing the shared Folder1, subFolder1, and FileA copy/move scenario described in the issue, then inspect the resulting server logs; the report provides no source file or test entry point. Done means copying or moving the file succeeds once and the resulting file downloads without corruption.
