When using Blender's file explorer to open an image (with image thumbnail generation enabled), blender will instantaneously crash if it enters a folder with an extremely high resolution image. The crash isn't a freeze, nor does it lock up the rest of my computer. It brings up "Blender is not respanding and must close" window.
I thought it might be a RAM issue, but I monitored the RAM as I entered the folder, and it never even had time to fill, for it crashes only milliseconds, if not instantly, when entering the folder.
If I disable the thumbnail generation, Blender will crash only when opening the file (still instantly though, same manner).
I tested it for a file format issue, and it has no problem with opening files of the same format at a smaller resolution.
This was also tested with only the image in a folder, no other files.
Windows is still able to generate a thumbnail for the image, and the image can still be opened and accessed, so its not corrupt.
The image that causes the problem is a 3,732 MegaPixel (86,400 x 43,200) 1.46GB TIF format image.
Blender can still easily open an image 1/8 the resolution and size (467 MP).
I was unable to test any resolutions between those two resolutions because of the time required to generate such images.
Blender 2.57.0, r36147, 64-bit
Windows 7 64-bit

Ah that makes sense, but why does it crash instantaneously? It takes about 45 seconds or so to generate a thumnail or load in a picture around 500 MP, but for the really high res one it just doesn't seem to even try, as if it gives up right when it sees it and crashes.
**Although I know this isn't any major issue (since I doubt anyone has ever really tried or needed to use an image so big), but I thought it would be good to bring it to your attention anyway :)
