Error message from dpkg

[Poe-Min Oliver Wu <pm5@matilda.fiorile.org>]

        This is the message thrown back when I run apt-get:
==
(Reading database ... dpkg: error processing /var/cache/apt/archives/apache-doc_1.3.9-13.2_all.deb (--unpack):
 files list file for package `doc-linux-zh' contains empty filename
Errors were encountered while processing:
 /var/cache/apt/archives/apache-doc_1.3.9-13.2_all.deb
Processing was halted because there were too many errors.
E: Sub-process /usr/bin/dpkg returned an error code (1)
==

        And this happens for everything that works through dpkg. 
        It seems to be a broken file since the power down
        not long ago, but I still can't find a way to fix it.
        Any suggestion?  Thanks.
