Error -3 means that calling the perl function link (between a file in
the pool and a name in the pc tree) failed.

Try manually doing something like the following from the command line:
link b32585c3cc30b7ebb556d335a08554e3 
/media/disk/pc/steve/151/f%2f/froot/f.gconf/fdesktop/fgnome/faccessibility/fkeyboard/f%25gconf.xml


Potential reasons:
- Files are on different filesystems
- File system you are using doesn't allow hard links (what filesystem
  are you using)
- Pool file somehow got erased before MakeFileLink was called or pc
  tree got erased
- File system full (?)

I guess I would ask what have you changed lately either for BackupPC
specifically or on your setup in general?
