>Description:
Current tar (1.11.2) clobbers existing archives if called with:

tar zcvf test.tar.gz

when you meant to type:

tar zxvf test.tar.gz

This is, of course, a stupid typo, but more current tar versions (for example 1.13.17), detect and prevent the silliness:

$ tar zcvf test.tar.gz 
tar: Cowardly refusing to create an empty archive
Try `tar --help' for more information.

>How-To-Repeat:
See above.
>Fix:
Please consider upgrading tar :-)
