konsole output from ark

Here's the output from konsole, even though it correctly shows it extracts the archive it only extracts a small part of it

I don't know if this is a duplicate of: 
https://bugs.kde.org/show_bug.cgi?id=179914

since I am using kde4.2rc1 (or maybe even a bit later)

I couldn't reproduce this with 4.2 version. Could you maybe try the same procedure as I did to see what happens?

1. Create a 1 gb file called big
$ dd if=/dev/urandom of=big bs=1024 count=$[ 1024 * 1024 ]  
2. Get the md5sum (and copypaste it somewhere)
$ md5sum big
3. Compress this file into roughly 80 pieces of 12mb each
$ rar a -v12m -m1 myarchive big 
4. Delete the file
$ rm big
5. Unpack the multivolume archive using ark
$ ark -b myarchive.part01.rar
6. Get the md5sum again and check if it is the same as step 2
$ md5sum big

I simply cannot understand how RAR can tell you in the log output "All OK", and there is still a problem with the files extracted. Ark does not infer at all with the extraction output; it just waits for it to finish.

ark works with the newly created archive but still fails all my other multipart archives whilst they are all correctly extracted by squeeze or fileroller

I have tried extracting the archive it seems to extract once every 8-10/times, the filesizes of the failed extractions, created are not always the same though.

Here to runs, the top run correctly extracted the archive, the second (bottom) rurun failed

It gets even stranger, I was just trying to extract the archive a couple of times and then plasma crashed; I didn't see any system tray extraction/filecopying notifications anymore but the file did extract correctly afterwards all the time, whereas before it was only 1/10 times 

Does it still happen to you (with KDE 4.2.2 or trunk)? If so, can you attach a small multipart rar archive that presents this behaviour or point to any?

Known bug, fixed somewhere in 4.2.
4.1.96 is an old, unstable version.
