http://moneroblocks.info/ looks good. But, as Primer pointed out... maybe there's still some issue even with 0.9.1 wallets and mining.... try to upgrade to 0.9.3 and resync? or maybe your pool was linked to a peer that submitted and old style block?
not sure if version exclusions were added to the code without looking at it....
It seems the peer submitted an old style block, all good now.
