In a large bowl, whisk together flour, salt, and pepper. Dredge rabbit in flour mixture, shaking off excess.
In a large Dutch oven, heat oil over medium-high heat. Add onion, carrots, and garlic; cook, stirring frequently, until tender. Add rabbit, and cook until browned, 4 to 5 minutes per side. Add wine, scraping browned bits from bottom of pot with a wooden spoon. Add stock, prunes, vinegar, rosemary, and thyme. Bring to a boil over medium-high heat; reduce heat, cover, and simmer until rabbit is tender, 1½ to 2 hours. Serve over mashed sweet potatoes. Garnish with rosemary, if desired.
