One think to watch when you change inner tubes (and I think this is what happened to you) is to ensure that the rubber innter tube doesn't get "pinched" between the wheel rim and the tyre - this causes lots of stress on the inner tube and leads to it bursting - sometimes it will burst as soon as you inflate the tyre, and sometimes when the tyre's under load.

Was their obvious damage to your rear tyre - i.e. could you see what caused the tube to explode?

I didn't see the old inner tube after the bang, and the tyre looked much the same as before (i.e. damaged in several places). When I changed the tube on Sunday, I did have some trouble getting the bead of the tyre to go in properly (so that it wasn't pinching the tube), and that may have been what went wrong; that's partly why I asked them to do the replacement for me yesterday.

Yes, it can be fiddly - and is in fact more fiddly the smaller the wheel is.
