tortoise svn cant open file the handle is invalid

When i am trying to use tortoisesvn on windows to do an update, i keep getting the following errors for a specific folder.

Can someone please let me know how to fix this problem and how it occurred?

Can't open file 
'C:\Users\myname\Documents\projects\cpe\lab\.svn\tmp\text-开发者_开发技巧base\con.svn-base': 
The handle is invalid.

Thanks

con is an illegal filename in Windows. Rename the file via Repo Browser to conform to MS's rules.

msdn.microsoft.com

This fixed the issue.
