Well, it depends on a few factors:
1. What style of beer is it?
2. What was your planned OG/FG
3. What yeast did you use, how much did you pitch, temperature, and how much time did you give it?
4. How much priming sugar did you use to bottle it?
Each of those could have a factor in why the FG was so high, but you don't necessarily have bottle bombs yet. You get bombs when your fermentation stalls out for some reason and then jumps into high gear when you introduce more simple sugar for it to consume. With a 1 gallon batch, I'd lean towards there being a little more yeast still in suspension unless you cold crashed your carboy.
At this point, if your beer is a heavy style, or its FG was only supposed to be about 5 points lower, or if your fermentation went exactly as planned, or if you nailed your priming sugar addition, I'd just keep an eye on the bottles. Some crystal malts can leave a lot of unfermented sugars in the beer after primary, so it bumps up the FG a little. Wherever you have them sitting for conditioning, make sure it's not next to your mink coats and silk kimonos. What I've seen people do is put them in a rubbermaid large storage container with the top cracked just a little. That way if you do have an explosion, it's neatly contained and easily washable. Don't put the lid on all the way because there may be enough pressure to pop that sucker off, and then you're exactly where you would be without it.
