I can't find the thread but there was a guy awhile ago that lost some coins when he was trying to move them to a new wallet. The problem had something to do with the new wallet he made not having generated all of the addresses it was supposed to, or something along those lines.

I'm setting up a wallet on machine I intend to keep unconnected to the web and want to make sure I don't repeat the same mistake. So how can I make sure I'm doing it properly?

Thanks.

Here is an unofficial observation from me: the wallet file is about 32 kbytes before this happens, and around 90 when it has.  It seems to happen when you generate two or three addresses.  However, I offer no warranty for this observation.  Use at your own risk.

Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable.  I never believe them.  If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins.  I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion.  Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice.  Don't keep coins online. Use paper wallets instead.

Running a getinfo() RPC command seems to be enough…

~164k for me. 42MB for a 100,000 address wallet.  Cool

... want to make sure I don't repeat the same mistake.
It's simple: Make a backup AFTER you finish the transactions you want, not BEFORE. Assume that a backup is worthless as soon as you use it again, if you plan on deleting your unencrypted wallet. The key pool should only be depended on in emergencies, so only depend on it for the regular backups you make of your spending wallet, NEVER for your savings wallet.

My recommendation would be to click on the Address Book button in the BitCoin client and count how many receiving addresses you have.

I could be wrong though.

That was an old bug. The newest version now creates all the addresses listed during first run. Before 1 was made but the next 99 wouldn't be generated till a transaction was done. If you are worried send a tiny bit to those addresses you are saving to. Once you have a completely up to date block chain with those transactions confirmed save the block chain on a usb stick. You can see the transactions on your offline computer just by copying the block chain over and see if it worked. You don't have to connect to check it!!
