[Csync2] Format Error

[Dan Brown]

I recently started getting a format-error during a stats sync.  These are on
Fedora FC6 servers which might be susceptible to the /dev/random problem
since I can't get SSL to work.
The following is debug output from attempting to sync.  The format error is
blocking all other updates.  I ended up removing the file since it's just a
stats files from webalizer but the server doing the update still can't do
the update.

My hostname is nitehawk.zu.com.

Format-error while receiving data.

Even from this debug, I see no obvious problem as to why it's not updating.
I've not yet wiped out and re-initialized the database to see if that will
help but I may try that next.
