For what it's worth, I was getting that error a LOT when using cscvs.
However, I recently updated to cscvs--experimental--1.1--patch-77 and
the problems have all gone away.

One detail easily missed is that the
I-Just-Want-To-Use-It-To-Sync-With-Arch instructions in the README
have altered slightly.  For example, the initial import is done "by
hand", not with cscvs -i as previously.

I have found that by following these updated instructions precisely, I
have been able to make cscvs process successfully a substantial CVS
repository with nigh on five years of edit history.  Quite impressive!

One small point: it would be nice if cscvs had a simple way of getting
a list of every filename path which appears in a given range of
patchsets.  (Perhaps it does and I missed it).  The method I came up
with was 

     cscvs log -P<branch> | awk '/^\t/ { print $1; }' | sort | uniq

which works if it can be assumed that no line in the log messages will
begin with a tab character.  (Of course, the nice thing about cscvs
using sqlite is that you can fairly efficiently query the patchset
information directly.)

That notwithstanding, cscvs is a wonderful tool, and I'm ever so
grateful to Charles and others for their efforts.
