I reckon it's probably trying to back up a mounted filesystem that's not a 
real filesystem and contains virtual files that could confuse it. For 
example, /proc or /sysfs.

You could try running from the command line with -v 9. Pay close attention 
to the last line output, that may tell you what it's trying to back up.

If that doesn't help, try running the strace command on the running 
rdiff-backup process, which should tell you what system call it's hung up 
executing. If that doesn't help you, try posting the output here.

Cheers, Chris.
