Yep! That's where the stellar comes in. It's something that everyone the network can accept and requires no trust. So as long as someone is willing to convert your gateway's credit to stellar (and worst case, your gateway should be willing to do so), you're fine.

That's assuming your gateway has stellar on hand to provide as conversion. Stripe is starting with 2% of the stellar, but (AFAIK) nobody else is starting with any significant chunk. If a gateway issues credit in exchange for real-world exchanges, I don't see why there's any expectation that they'll have stellar on-hand to use for the conversion, although perhaps they can use their real-world money to buy stellar from some other gateway.

I'm also wondering, since the amount of Stellar is capped (100 billion, right? Can this ever change?), and since 50% of Stellar is being distributed to people who sign up, it seems like a sizable portion of this Stellar will almost certainly immediately become unusable as people sign up, get their Stellar, and never come back.

Edit: Just found the bit where it says Stellar will be created at a rate of 1% annually. The fixed 100 billion cap I cited was based on earlier comments about Ripple's cap.

That's not the only way that gateways can talk to eachother. Given this is ripple we're talking about, anyone who has a mutual trust connection between gateways can facilitate a transaction, as can any market-making trader.

Looking at MIRI's gateway and my own showed dozens of such connections. Ripple has 100,000 users, any of which can be part of the connection between any two given gateways. Stellar is planning on growing that large and larger, so it should be expected that this will happen there, too.

Isn't the worst case that the gateway goes belly up?

Well, the real worst case is probably that the Earth gets hit by a coronal mass ejection and takes down all electronics: http://bit.ly/1qO25PH :).

But more seriously, a gateway you trust going under is indeed a risk. That's part of why you can specify not just "I trust this gateway" but also "I trust this gateway for up to 100 CAD" — you can explicitly specify your exposure.
