Nightly build file Ubuntu is corrupted

The nightly build 2014-04-14-21-02-5363f93 is not possible to decompress under Ubuntu. The previous (mscore.64bits-2014-04-12-09-03-b424d8e) works fine.

see terminal output:

>>>tar -xjf '/home/xxxx/Downloads/mscore.64bits-2014-04-14-21-02-5363f93.tar.bz2'

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.
