Linux Nightly build may be corrupted

Hi,

I'm new to the forum, so I apologize if I'm posting to the wrong place. It seems that this Linux build is corrupt:

mscore-2013-09-20-19-18-c84969b.tar.bz2

The file is only 480K (downloaded 3 times to triple-check), and when trying to extract, I get the following error:

kevi@ubuntu:~/Downloads$ tar xvjf mscore-2013-09-20-19-18-c84969b.tar.bz2
mscore

bzip2: Compressed file ends unexpectedly;
perhaps it is corrupted? *Possible* reason follows.
bzip2: Inappropriate ioctl for device
Input file = (stdin), output file = (stdout)

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.
