[Duplicity-talk] IOError [Errno 22] problems

[Shane O'Donnell]

I am using version 0.6.06 and am getting the error below.  I also got a similar 
error using 
version 0.4.12.  Can anyone suggest a cause for this or point me in the right 
direction if a 
solution is already known.  

Regards,
Shane.
