Maven 2 tar.gz issues

I reinstalled my local copy of maven2 recently, and thought I’d add into to google a problem I experienced trying to unarchive the tar.gz or tar.bz2 flavors of their binary distribution. (.zip files seem fine)

The problem shows itself while extracting — tar reports “tar: A lone zero block at 2970”. Some googling seems to trace the problem to a maven/ANT lib problem encoding tar files. I got this with both 2.0.8 and 2.0.7, possibly with other releases as well.
