Found during testing of bug 5560.
Scenario: Export c:\ and create file from ThinLinc server
Given ThinLinc client running on Windows 7
And exported c:\ with read-write
When Creating a file "foo.txt" in "~/thindrives/c" from ThinLinc server, 4 bytes long
And Copying (a bigger) "foo.txt" from Desktop to "c:\" as administrator
Then "~/thindrives/c/foo.txt" should be the second file[*]
However, in my testing, the file length is from the first "foo.txt", but the file content is partially from the second "foo.txt", truncated to 4 bytes.
[*]: I've failed to find any official documentation, but running "notepad c:\foo.txt" locally will give you the second file.
This bug is present both with build 6157, as well as 4.10.0-6072. It happens even after disconnect/reconnect, and even if changing ThinLinc server.
