dpkg issue

["Mark A." <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
