Bug report : Important crash of EoG

[Nathan Vogel <vogel nathan gmail com>]

Hello !

First of all, thanks for this great software :)

BUT, I found a pretty big bug that caused my whole graphical session and every other opened program to crash.

I didn't use the bug tracker, because I don't know if I can upload images, I don't have an account and there wasn't a lot of EoG bug reports. 

Here is what happend :

wallpaper-87028.jpg , the file (in this e-mail) is an image downloaded on wallbase.cc.

I use ffmpegthumbnailers for the thumbs images (it's really incredibly fast and compatible and should be Ubuntu's default b.t.w, seriously, why not ?) and the thumb was perfectly generated.

I opened it with Eye of Gnome and displayed an error : (sorry, it's a bit in french)

> Erreur d'interprétation du fichier d'image JPEG (Not a JPEG file: starts with 0x89 0x50)

I looked in the file proprieties : 

  --> under the General tab : Type : image/jpeg

  --> under the Image tab : Type : png

I changed the extension from .jpg to .png

I opened the image again.

It almost immediatly shut the graphical session, very briefly showed some text console message and took me back to Lightdm.

When I logged back in, all my programs were closed.

I tried once more, and this time I had to wait a few seconds more to make it crash again. (I could see the image this time, it seems to lack a few pixel somewhere)

if I open the image in firefox, there are no problems.

So I know this is most certainly a corrupted file, but I have like 2% percent of my wallpapers that seem to be corrupted and it's a lot !

I think that such a huge bug caused by a simple file extension change should not happen.

And there is the strange thing with the file type showing in jpg and png... ?

My config :

Ubuntu 12.04 LTS with Gnome Shell on a Dell Inspiron 15R Special Edition.

3rd generation Intel® Core™ i7

2Go AMD Radeon HD 7730M   (I'm using the latest amd proprietary drivers)

SDRAM DDR3 8 Go à 1600 MHz

Sorry for my poor english skills.

Thanks a lot !

Nathan
