Comment 22 for bug 195798

I just want to add that I too encounter this bug on CIFS shares, which is mildly annoying. It seems like Konqueror encounters the same problem, it gives you the option to overwrite, but that doesn't do anything (I'd test other file managers, but I don't have them installed, but could somebody test Thunar or other file managers?). The CIFS shares aren't running on Windows (one is on OS X, another one is embedded Linux).

So I suspect this is a bug in CIFS or whatever's between CIFS and the file managers (unless both file managers implemented the same bug).
