dpkg issue

[Mark <markthema3@gmail.com>]

I have an error in dpkg where whenever I try to install a package, it
gives me this error:

dpkg: parse error, in file '/var/lib/dpkg/available' near line 11991
package 'vinagre':
 `Depends' field, reference to `libvte9': version contains ` '

I can't figure out how to fix this. Any help would be nice. I am using
the Ubuntu 10.04 LTS distro.

Thanks,
Mark
