System: NetBSD Mandylion 2.0_BETA NetBSD 2.0_BETA (Mandylion) #8: Tue Apr 20 20:57:35 CEST 2004 juan@Mandylion:/home/juan/httpd/nbsd/obj/sys/arch/i386/compile/Mandylion i386

NetBSD Nocturno 2.0E NetBSD 2.0E (Nocturno) #106: Sat Apr 24 16:47:54 CEST 2004  juan@Nocturno:/home/juan/build/obj/sys/arch/i386/compile/Nocturno i386

>Description:

	NetBSD -current is not able to decompress some .tar.gz files,
	as for example unpacking pkgsrc/textproc/crimson's distfile.
	
	Same tarball was unpacked succesfully in 2.0_BETA without any
	problem.

>How-To-Repeat:

	Install NetBSD -current (2.0E) and try to install pkgsrc/textproc/crimson:

$ cd pkgsrc/textproc/crimson && make
===> Checking for vulnerabilities in crimson-1.1.3
=> Checksum OK for crimson-1.1.3-bin.tar.gz.
===> Extracting for crimson-1.1.3
===> Required installed package kaffe>=1.1.4: kaffe-1.1.4 found
==========================================================================
The following variables will affect the build process of this package,
crimson-1.1.3.  Their current value is shown below:

        * PKG_JAVA_HOME = /usr/pkg/java/kaffe
        * PKG_JVM = kaffe

You may want to abort the process now with CTRL-C and change their value
before continuing.  Be sure to run `/usr/bin/make clean' after
the changes.
==========================================================================
tar: Invalid header, starting valid header search.
tar: End of archive volume 1 reached
tar: Unexpected EOF on archive file
*** Error code 1
