[volunteergrid2-l] some error

Sat Dec 17 07:19:04 UTC 2011

Acutally i started seeing this error when i moved my desktop to linux..and
this particular directory that i am backuping is scp copied from a Windows
machine.
That`s why i started using convmfs - because i had many errors during
backup for filename encondings..

However today i again got:
 re-using old directory for '/home/ianchov/testmount'
