Backup deja-vue fails starting at line 151

Hello
I have Ubuntu 11.10 installed and started using Backup to Ubuntu Cloud.
It was working on a daily bases. Then started failing. It will backup manually.
Is this a program problem or due to my machine?
Any suggestions on how to correct this problem greatly appreciated
Thanks Cliff
