Error Description: When viewing hdr images in the file browser with thumbnails enabled blender will crash. When an hdr is opened using the list view, opening the "browse image to be linked" drop down will crash blender.
Exact steps for others to reproduce the error
Open new scene. Assign environment texture to world. Click open and change file display mode to thumbnails. Open a folder with an hdr image. Blender will crash.
If an hdr is loaded by not using the thumbnail preview mode then anytime the image datablock drop down menu is opened blender will crash.
