23.0.50; Possible bug with bzip2 compressed tar files?

[Peter Dyballa <Peter_Dyballa@Freenet.DE>]

Hello!

There seems to be a problem with bzip2 compressed tar files. It does  
not happen with every such file. It does not depend from the file  
size, or the block size used by bzip, nor the file name  
extension, .tar.bz2 or .tbz2 or .tbz. One stable element is that the  
files all come from one source: The Omni Group! I can't be more  
specific, because the files are fetched by the web browser OmniWeb  
from some site and saved locally inside a UNIX file system. The saved  
archives are almost 15 MB in size – which I probably can't send by  
eMail, FTP would be an option. I'll also contact the Omni Group.

Using tar (versions 1.14 +CVE-2006-0300 +CVE-2006-6097 or 1.16.1,  
bzip2 Version 1.0.4, 20-Dec-2006) on the command line, I can list the  
archive's contents and also extract files:

	tar: Record size = 8 blocks

The error happens also in GNU Emacs 23.0.60 and in GNU Emacs 22.1.50.

Not using View mode because the major mode is special
