OC v4.0.1 Debug shows can't find csync files

[helicopterjeff]

Just updated to 4.0.1. The log file is loaded with these:

{"app":"files","message":"getFileId(): file not found in cache (\/jeff\/files\/csync_unix_extension*test.ctmp)","level":0,"time":1338837668}

I've got permissions set for the httpd service to write to everything.

Is this something to worry about? I'm logging in debug due to other issues with 4.0.1
