[Box Backup] Redundant locations not removed?

That's very interesting, the errors in the logs put me off suspecting 
this.

Jul 25 20:02:30 yoiko bbackupd[24426]: SSL err during Write:
   error:1409F07F:SSL routines:SSL3_WRITE_PENDING:bad write retry
Jul 25 20:02:30 yoiko bbackupd[24426]: Exception caught (Connection
   TLSWriteFailed (Probably a network issue between client and server.)
   7/33), reset state and waiting to retry...

Did you have anything in the server logs around this time, lime an 
exception?

Also, we should probably catch this one and report the error properly:

Jul 25 10:59:54 yoiko bbackupd[402]: Connection made, login successful
Jul 25 15:06:14 yoiko bbackupd[402]: Exception caught (Connection
   Protocol_UnexpectedReply (Server probably reported an error.) 7/47),
   reset state and waiting to retry...

Older clients (e.g. 0.10) should not back up above the soft limit, so they 
would never have got so far. Newer clients (like my branch) will 
ignore the soft limit and back up to the hard limit.

So you should probably lower the soft limit permanently to ensure that 
there's always free space after housekeeping for however much new data 
needs to be uploaded.

Cheers, Chris.
