I was just having a look into my debug.log file when I found what it seems like a generated block:

However it seems the 50.08 have not appeared in the client balance yet:
    "version" : 32002,
    "balance" : 0.00000000,
    "blocks" : 119044,
    "connections" : 23,
    "proxy" : "",
    "generate" : false,
    "genproclimit" : -1,
    "difficulty" : 92347.59095209,
    "hashespersec" : 0,
    "testnet" : false,
    "keypoololdest" : 1300848900,
    "paytxfee" : 0.00000000,
    "errors" : ""

When I check the transaction 47bc44f881 in blockexplorer I see that in the transaction Input is "Not yet redeemed" (

Anything this newbie is missing?

You must wait 120 blocks, before it "matures."

Immature generation transactions currently do not show up in JSON-RPC queries. There is a patch to fix this, and it will probably make its way to the official client in the next few releases.

Thank you for your answers.

I found some posts relevant to this, I am posting them for reference:

Maybe it would be useful to add this info about maturity to the FAQ?
