[imp] DIMP: wtf ?

[Mário Gamito]

Hi,

I've just installed dimp.

When i go to its page, it offers me to save a x-json file !!!

If i save it and then check its contents, i can see:
--------------------------------------------------------
<br />
<b>Notice</b>:  Use of undefined constant SERIALIZE_JSON - assumed 
'SERIALIZE_JSON' in <b>/home/www/horde/dimp/lib/DIMP.php</b> on line 
<b>356</b><br />
<br />
<b>Catchable fatal error</b>:  Object of class stdClass could not be 
converted to string in <b>/home/www/horde/dimp/lib/DIMP.php</b> on line 
<b>356</b><br />
----------------------------------------------------------

The mind boggles.

Does anyone has any insight on this ?

Best Regards,
