[Semediawiki-user] Install issues

[Tathagat B. <u25...@an...>]

Hey,

I am having the same sort of issue that [Semediawiki-user] Fatal error: 
Unsupported operand types in includes/SMW_GlobalFunctions.php on line 
307 at 
http://sourceforge.net/mailarchive/message.php?msg_name=b9e01c040801031450n88a85adg9954b2aa591caadd%40mail.gmail.com 

 
If it was a bug it would stop the install cold so I figure I'm doing 
something wrong.  
 
Tried to fix it the same way as mentioned in the above post, namely 
added a if (!is_array($wgNamespaceAliases)) { 
$wgNamespaceAliases=array(); } line before line 307.  
 
This seemed to fix it but i tried to Special:ExportRDF the main page at 
http://localhost/wiki/index.php/Special:ExportRDF/Main_Page and got  
 
Database error
A database query syntax error has occurred. This may indicate a bug in 
the software. The last attempted database query was:
 
(SQL query hidden)
 
from within function "SMW::getSpecialValues". MySQL returned error 
"1146: Table 'interinteldb.smw_specialprops' doesn't exist (localhost)".
 
I guess I'm doing something silly, can someone help me out.
 
I'm using a wamp server on my localhost. It isn't online and its a new 
wiki so there is no data in it. The only changes made to it are that I 
added some code to the LocalSetting.php that is similar to 
http://jrandomhacker.info/LocalSettings . Its mostly permissions so it 
shouldn't be an issue.  

Also :  
 
The wiki works otherwise (-semwiki) and my setting are Apache 2.2.6 , 
PHP 5.2.5 , MySQL Version 5.0.45.

to add sem wiki i did  
 
#extension 
include_once('extensions/SemanticMediaWiki/includes/SMW_Settings.php'); 
enableSemantics('127.0.0.1');           --- mostly cause i'm playing 
with it on my system

 
Regards
