<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Maybe this should be "while we haven't read 1024 bytes", but of course the file could be smaller than that so it would have to check for that too.
What I mean is: I assume peek() doesn't wait, so if the first packet we get is 48 bytes, we have only 48 bytes. Don't know if this is a real problem in practice though, feel free to ignore this comment.</pre>

Perhaps a good compromise would be to wait for the 1024 bytes whenever the size of the content to be retrieved is known to be larger than 1024 bytes ? That way for the large enough files, we have a better success of getting a more accurate mime-type and for the others well we do the best we can. :) I will see what I can do about it. For the record, I did test this change with a small enough file, ftp://ftp.kde.org/pub/kde/README_UPLOAD, which happens to be only 404 bytes. Here is the log:
kio_ftp(2902) Ftp::copy: ftp "/pub/kde/README_UPLOAD" -> local file "/tmp/kde-dalemayehu/konqueroraj1566"

I will see what I can do about improving the code as suggested...

That way kio_ftp will work correctly if and when it is put on hold to be reused from another application. Note that the patch uses QIODevice::peek to achieve this goal.</pre>
