cvs转换svn时出现异常的问题

cvs转换svn时
python cvs2svn -s f:\svn\bjhmcms e:\HMCMS --encoding=gbk --fallback-encoding=utf-8
执行此命令出现以下错误

ERROR: svnadmin failed with the following output while loading the dumpfile:
svnadmin: E125005: Invalid property value found in dumpstream; consider repairin
g the source or using --bypass-prop-validation while loading.
svnadmin: E125005: Cannot accept non-LF line endings in 'svn:log' property

请问此错误如何修改,谢谢!
