Nautilus crashes (and blocks the entire system) when the user tries to view a gif file's properties.

[Andreu Correa Casablanca]

System: Ubuntu 11.10 64 bits, Laptop with Core 2 Duo 2.8Ghz + 4GB RAM + Integrated Intel graphics card

Package version: libexempi3 (2.1.1-1build2)

When I try to open the properties dialog over a GIF file, my computer gets blocked and the memory consumption grows fast as light... (more than 3GB of RAM in 2 seconds).

In computers with more CPU power (and more memory), the system don't became blockec, but the properties window take much more time to be loaded with GIF files than with other image types, such as PNG.
