Promoting a slave to master gives syntax error

[Theodotos Andreou]

Thanks for the tip Mark. Now all the zone files are cached as text.

Now I have a different problem. After converting alll the zones to 
master many zones failed to load because of this:

# grep example.com /var/log/syslog

29-Apr-2014 11:21:32.692 zone example.com/IN: not loaded due to errors.

Any idea why? Is there a configuration setting to ignore these errors?
