I tried resizing a lightprobe with hdrshop then render it with map_type 7 on
a sphere but no crash. What was the size of the image ?

There is a limitation in the current Read_HDR_Image function : image width
must be < 2048 (with no test so if it s bigger => crash). It could easily be
corrected but i do not plan to release any new mlpov version, so you'll have
to wait for a megapov with high dynamic range images support (or recompile
mlpov with a buffer size > 2048)
