I observe similar behaviour with Bacula 5.2.* on CentOS 6, also with
a Windows client. (2003 x86 in my case)

Restores to the Windows client systematically crash the FD on the
client without restoring anything. This seems to be a known, as
yet unsolved problem. There are several posts on this on the list.

Restoring the same files to the Bacula server instead works inasfar
as the files are restored correctly, but crashes the FD on the
server in the end, leaving a backtrace file in the Bacula working
directory:

I wonder what would happen if I tried to restore a file that
has been backed up from a Linux client to a Windows client.
