[QA] moving encrypted file to unencrypted FTP storage and back causes a decrypt error

[jnweiger]

Seen with v1.5.1-rc1 on 10.7.0 with user key encryption enabled.

• disable encryption for an SFTP external storage.
• upload a textfile hello_ftp.txt to the main storage, it gets encypted. OK
• use the Web UI to move the file into the SFTP storage. It gets decrypted. OK
• use the Web UI to move the file back to the main storage, it sometimes gets encrypted, sometimes the move fails, (Okayish? se below!), but also an error appears:
  

Expected behaviour: no useless error messages.

No error message appears, if the file is created inside the unencrypted SFTP storage, and then moved out.

Re-tested with 1.5.1-rc1 and hsmdaemon-0.0.8 enabled:

• Same diagnostics.
• The move back fails. The file is not re-encrypted. It remains unencrypted in the SFTP storage. BAD.

Fixed in 10.8.0

We want to release it together
