Bug#505819: vim-runtime: File conflict during upgrade from (older) version

[Frans Pop]

Package: vim-runtime
Version: 2:7.2.025-2
Severity: serious

During an upgrade of an unstable sparc system that I don't boot very often,
I ran into the following error.

Preparing to replace vim-runtime 1:7.1.314-3 (using .../vim-runtime_2%3a7.2.025-2_all.deb) ...
Adding `diversion of /usr/share/vim/vim72/doc/help.txt to /usr/share/vim/vim72/doc/help.txt.vim-tiny by vim-runtime'
Adding `diversion of /usr/share/vim/vim72/doc/tags to /usr/share/vim/vim72/doc/tags.vim-tiny by vim-runtime'
Removing `diversion of /usr/share/vim/vim71/doc/help.txt to /usr/share/vim/vim71/doc/help.txt.vim-tiny by vim-runtime'
dpkg-divert: rename involves overwriting `/usr/share/vim/vim71/doc/help.txt' with
  different file `/usr/share/vim/vim71/doc/help.txt.vim-tiny', not allowed
dpkg: error processing /var/cache/apt/archives/vim-runtime_2%3a7.2.025-2_all.deb (--unpack):
 subprocess pre-installation script returned error exit status 2

Feel free to downgrade or close if you are sure this affects only the
intermediate versions and not e.g. Etch to Lenny upgrades.

I'll leave the system in this state for a bit in case more info is needed.
