Cannot view a revision with CVS 1.11.9

[Anderson, Robert H - MWT]

I get the following error when I click on the revision number of a file...

Error: Unexpected output from cvs co: /app/common/bin/cvs: invalid option --

Everything was working fine before I upgraded from CVS 1.11.

Any help would be appreciated. Thanks,
