No "component=Semantic MediaWiki" on Bugzilla
There's neither a product or component "Semantic MediaWiki" on Bugzilla (https://bugzilla.wikimedia.org/query.cgi?format=advanced) which makes finding and reporting bugs pertaining to SMW a bit cumbersome.
Reported as a bug at https://bugzilla.wikimedia.org/show_bug.cgi?id=43484
I closed this bug as invalid since it is all there. Cheers
