No, but I haven't tried ontology import.
Here's my guess at what might be happening.
Instead of loading the PHP code for every datatype on every request to
MediaWiki, SMW does lazy-loading of the PHP file implementing each
datatype as needed. So SMW_Datatype.php tells itself (in
announceTypeHandler() calls around line 286) that email,uri, url, and
annouri datatypes are implemented by class SMWURITypeHandler in
SMW_DT_URI.php , but doesn't actually include this file.
Somehow the lazy-loading is broken in your case. Please update to
latest SMW if possible, and file a bug including your version numbers
from Special:Version.
A possible fix is to explicit put
## My temp Workaround for ontology import bug
global $smwgIP;
include_once($smwgIP . '/includes/SMW_DT_URI.php');
towards the top of SMW_Datatype.php, just after
require_once('SMW_DT_Float.php');
to force the code to be loaded.
Good luck,
