Cvs2svn dies with "dbm.error: cannot add item to database"

I am trying to convert a ~5000 file CVS repository using the cvs2svn.py
included with 0.24.2. It appears to be working fine until it dies in
pass 4 on the 142nd file.

If I remove the directory it was working on from the source CVS
repository copy, cvs2svn fails the same way in the next directory (on
the 142nd file again, coincidentally or not). It appears some kind of
size limit is being exceeded.

Here's the interesting portion of the output:

dbm.error: cannot add item to database

I don't know much about dbm or Python, so I don't know what else to do.
I believe Python is using ndbm.

I did modify and rebuild Python, changing its dbmmodule.c so that it
gave me a little more info about the failing call (to dbm_store), which
changed the error message to:

dbm.error: cannot add item to database in dbm_ass_sub; dbm_error
returned 2

I think this might be a "Block size error".

Any ideas?
