Has the CVS repo been tampered with in the past? If so, it's entirely possible that checking out and working with CVS works just fine, but getting history into coherent changesets is impossible.

Can you checkout the offending (old) revisions using CVS? If so, there is indeed a bug in the cvs-importer. Otherwise, your CVS repo is hosed and you're reduced to running whatever conversion tool does the best job if you want to maintain history.

cvs2svn is apparently quite good at getting even the weirdest history right. Perhaps you can try that and then running "git svn" on the resulting svn repo?

Good luck. You'll probably need it :-/
