ERROR: ... lacks the proper padding sizes for an array with 2 dimensions

I'm not entirely sure what is happening here. I'm trying to filter an image before resizing it, as recommended by the Images.jl docs. Running:

reduction_factor = new_len/minimum(size(im)[1:2])
im = imfilter(im, KernelFactors.gaussian(0.75*reduction_factor))

Results in:

ERROR: ArgumentError: ImageFiltering.Pad{1}(:replicate, (2,), (2,)) lacks the proper padding sizes for an array with 2 dimensions

Trying out different padding arguments doesn't lead to much success except for the Inner() scheme, which is what I'm using for now (since I'm resizing from thousands of pixels on a side down to hundreds, so these boundary conditions don't matter much to me)

Reproduce the two-dimensional RGB image case from the report, then inspect the padding checks in ImageFiltering/src/border.jl and the imfilter call path in ImageFiltering/src/imfilter.jl. Done means the reported padding schemes handle the two-dimensional input without the padding-size ArgumentError, with coverage for the demonstrated call.
