[Gimp-user] 32bit float image opens white?

[Casey Connor <gimp-user-list caseyconnor org>]

I just calculated a median image from a stack using gmic 2.0.0 on the 
CLI. Worked fine, and the result image is 32bit float:

$ identify downstream_hi_median.tif
myfile.tif TIFF 3456x5184 3456x5184+0+0 32-bit sRGB 286.7MB 0.000u 0:00.000

When I open it in gimp (2.9.5 -- commit c175afbc) it opens as all-white. 
The layer preview thumbnail is fine, though, and changing precision to 
16bit integer the image appears correctly.

Is this bug known to anyone? I couldn't google anything up on it.

Thanks!
