  We report the discovery of a subtle infrared excess associated with the young
white dwarf EC\,05365--4749 at 3.35 and 4.6\,$\mu$m. Follow-up spectroscopic
observations are consistent with a hydrogen atmosphere white dwarf of effective
temperature 22\,800\,K and log [\emph{g} (\,cm\,s$^{-2}$) ] = 8.19. High
resolution spectroscopy reveals atmospheric metal pollution with logarithmic
abundances of [Mg/H] = --5.36 and [Ca/H] = --5.75, confirming the white dwarf
is actively accreting from a metal-rich source with an intriguing abundance
pattern. We find that the infrared excess is well modeled by a flat, opaque
debris disk, though disk parameters are not well constrained by the small
number of infrared excess points. We further demonstrate that relaxing the
assumption of a circular dusty debris disk to include elliptical disks expands
the widths of acceptable disks, adding an alternative interpretation to the
subtle infrared excesses commonly observed around young white dwarfs.
