Upload does not work, error in tree_hash function

Hi, this is the first time I'm trying to use the Amazon Glacier CMD Interface but with no luck.

I'm getting the following errors :

[ec2-user@ip-10-202-162-223 application-management]$ glacier-cmd -c glacier-cmd.conf --no-bookkeeping --loglevel DEBUG upload quipo "/home/ec2-user/application-management/backups/glacier/2013-11-18 - 11:35:59.gz"

I tried using those two commands, none of those commands seems to work :

glacier-cmd -c glacier-cmd.conf --no-bookkeeping --loglevel -1 upload quipo "/home/ec2-user/application-management/backups/glacier/2013-11-18 - 11:35:59.gz"
cat "/home/ec2-user/application-management/backups/glacier/2013-11-18 - 11:35:59.gz"| glacier-cmd -c glacier-cmd.conf --no-bookkeeping upload quipo --description "QUIPO Platform" --stdin

I'm getting the following in the logs :

I'm not really used to code using Python but it seems that the error comes from an access to an array with a not existing index ?

Do you know why this error appears ? Can you help me fix that with a quick workaround ?

Thanks,

Baptiste

Ok, I finally found the problem, the archive I tried to upload was empty.

Perhaps a check on the files to archive before beginning an upload would be helpful.

When you say, "was empty", do you mean the file was zero in size?
