Version:           4.6 (using KDE 4.6.1) 
OS:                Linux

So, for start - I enter sftp://username:passwd@ftp...cz . Dolphin ask me, for enter (and remember!!!) password - every time again and again!

When I got login, then I open zipped archive in dolphin, select files and then click drag them into sftp folder.

It start copying files, and notify me, that some files already exist - my option - SKIP all exist.

Then it continue. End with 306 files copyied. AND that's AMAZING! I wondering, why I can see files on websites. Maybe because they aren't THERE! It end with xx file, leave it one 0 b of some_file.part and even doesn't bother to tell me it failed.

I'm even not talking about freezing on my 2Ghz 64 bit computer, when I select 300 files and catch them with mouse and drag...! What's wrong?!

After that problem, it start telling me, that some folders in sftp doesn't exist (I guess sftp kio died with NO ERROR - even in konsole)

If SOMEONE want to make KDE better, I'm prepared give some time to help fix that issue (debug outputs, testing patches, addional information)

Reproducible: Always

Steps to Reproduce:
use ftps with zip file archive

Actual Results:  
Doesn't care if user think, it's fine...

Expected Results:  
At least give me a INFORMATION about failure! (not talking about fixing problem, it could be problem on sftp server side)

btw. I can copy that files with dolphin: file by file and it works!
