UPDATE:
Looks like this coin has also fallen victim to the negative target spacing problem that has plagued many other coins recently; however, this one seems to have failed much earlier. Last proof-of-work block was accepted around 8th October 2013. scrypt/proof-of-work mining would have stopped working at this time.
I tried a short run of test mining and the behaviour is identical to the other coins such as ADT, CDC, ORB etc which have the same bug: miner finds a block, but the client quietly ignores it, never announcing it to the network.
There is one strange difference I've noticed when compared to the other failed coins. My client appears to be minting proof-of-stake blocks that are of the same value (8+ Maples) as a proof-of-work block, but the network is reporting the expected smaller amounts of a proof-of-stake win (0.03 or lower)
My client says I generated this block and was granted 8.03843900:
{
"account" : "",
"category" : "generate",
"amount" : 8.03843900,
"confirmations" : 172,

But viewing block da42cd01bd50a31fa62dc92f88193b8b4cdcc8120ff4db293659a755b257610e directly, says the network only minted 0.01440100, and that it's a proof-of-

So although Maples can't be directly mined right now, it looks like those who hold a balance and keep their client running may be still able to mint normal block amounts. (?!) My balance is increasing, and I was able to send the entire amount to another address (which I realise now I shouldn't have done - no more PoS for a while!), so it looks like those 8+ PoS numbers my client is reporting are real.
I guess that leaves us in a weird elitist chicken and egg situation where you already need to have coins, in order to be able to generate new coins. Mind blown.
