dpkg: error processing
/var/cache/apt/archives/vim-doc_1%3a6.3-031+1_all.deb (--unpack):
 subprocess pre-installation script returned error exit status 1
Errors were encountered while processing:
 /var/cache/apt/archives/vim-doc_1%3a6.3-031+1_all.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

I think the // indicates that an empty string which should have been
vim-doc has been lost somewhere. 

I had a look at the prerm script and found that it's only calling
debhelper scripts. So I guess the bug is not really in vim-doc but more
in the debhelper scripts....

BTW, my debhelper version was also upgraded in this upgrade and is now
4.2.24. 

Cheers.
