Unfortunately, the only content of the file was one line:

The file itself is only 20k of size.

Is there something I missed?
Is there probably a command line tool to do exports?
    

All you can do via the ZMI, you can do in an interactive Python
interpreter session -- however, it is unlikely that the result
will be different.

"Export" uses essentially the same mechanism which is used
by the ZODB itself (persistent references are expanded, though, rather
than stored as references). Especially, the export of an object
should contain all objects referenced (directly or indirectly) by this 
initial object.

If this does not work in your case, then it may be necessary to
debug the export process (to find out why it does not work).

  
Hi Dieter,

thanks for the reply.
I set the log levels to debug and got the following results in event.log:
2007-08-10T15:05:06 DEBUG txn.4 new transaction
------
2007-08-10T15:05:06 DEBUG ZODB.ExportImport broken reference for oid '\x00\x00\x00\x00\x00\x00\x00\x06'
Traceback (most recent call last):

2007-08-10T15:05:07 DEBUG txn.4 commit

Unfortunately,
from the logs I really cannot see what to do. Does anyone know? Any help is appreciated.
Thanks in advance.
Best regards,
Chris
