hi

have been getting following errors when tryign to upgrade my Debian sid box:

dpkg-query: parse error, in file '/var/lib/dpkg/status' near line
29666 package 'virtualbox-2.1':
 error in Version string `2.1.4-42893_Debian_lenny': invalid character
in revision number
exim4-config.postinst: [WARN] Installed debconf version is broken.

package 'virtualbox-2.1':

in revision number
E: Sub-process /usr/bin/dpkg returned an error code (2)
A package failed to install.  Trying to recover:
dpkg: parse error, in file '/var/lib/dpkg/status' near line 29666
package 'virtualbox-2.1':
 error in Version string `2.1.4-42893_Debian_lenny': invalid character
in revision number


Results in inability to upgrade any packages on the system.

Anyone come across this and know how to fix? or is a system re-install needed?
