accomplice testimony whenever a witness against the defendant might reasonably be considered an accomplice. State v. Henderson, 620 N.W.2d 688, 700 (Minn.2001); State v. Shoop, 441 N.W.2d 475, 479 (Minn.1989); State v. Moon, 717 N.W.2d 429, 436 (Minn.App.2006), review denied (Minn. Sept. 19, 2006). If the district court fails to give such an instruction, this court applies a harmless-error analysis. Shoop, 441 N.W.2d at 479. But the issue in this case concerns the application of a statute to the facts as found by the district court. Such a review is a question of law, which we review de novo. O’Malley v. Ulland Bros., 549 N.W.2d 889, 892 (Minn.1996) (stating that the application of a statute to undisputed facts is a question of law); State v. Bunde, 556 N.W.2d 917, 918 (Minn.App.1996) (<HOLDING>). Minn.Stat. § 634.04 (2004) applies to
