installing old version of flashplugin-installer leaves package in broken state.

Binary package hint: flashplugin-nonfree

When forcing an old version of flashplugin-installer, the installation fails. This leaves the package in an half-installed phase where (re)installation, (re)configuration and removal are impossible. Only by editting the postinst script can the package be removed.

Here are the log of the install and the attempted removal:
