Hello. I tried importing a .hdr, pretty low rez at 450x900, for the background in the Light>Background>Texture and ZBrush crashes every time. I tried importing a .jpeg and its fine, but of course that’s not the same. I’m on OS X 10.6.8.
Can you open your HDR in Photoshop, checking that it’s a 32 bits image, then saving it as a new file and then reimporting it in ZBrush ?
Also, can you provide us the HDR for internal testings ?
It’s a bug. You’ll have to use a jpg image

I created the hdr in Photoshop and it was definitely 32bit. What would be the best way for me to share that file?
