Ubuntu – How Do I manually remove malformed Packages

I tried to install typo3 via the apt-get package manager on Ubuntu 13.10 Saucy. During the installation the Package typo3-dummy could not be configured and remained in status: half-installed

sudo dpkg --purge --force-all typo3-dummy 
(Reading database ... 107326
files and directories currently installed.) Removing typo3-dummy ...
apache2-maintscript-helper invoked from a modified environment. Please
hint required arguments manually dpkg: error processing typo3-dummy
(--purge):  subprocess installed post-removal script returned error
exit status 1 Processing triggers for ureadahead ... Errors were
encountered while processing:  typo3-dummy

What else could I try to get rid of this package? I'd like to avoid fresh installation.
