Bug#650513: excessive backup pkgcache.bin files

This bug exists in stable, and it's very annoying on my side.  My
partition will fill up with these blasted files.  I think it's more
noticeable on my side because I use CRON-APT to update my security
patches for my VPS every 4 hours.  Every time it does that, it seems
like it creates another 45MB pkgcache.bin file backup.

Please backport this fix to squeeze!  I will go ahead and upgrade to
testing for apt, but this is severe enough to warrant a backport.
