I believe you need newer drivers, there are known problems with AMD drivers and Big Picture.
I have Gentoo AMD64 with nvidia-driver-319.17.
Steam as well crash every time I try switch to big picture mode.
I solved this issue by upgrading to open source drivers. This also solved some other issues, like Anti-aliasing in Half life 2.
This is still an open issue with the AMD drivers.
Sabayon amd64 with nvidia driver 319.32 and much the same issue, sorry to necro the thread.

That looks like a separate issue, can you open a new entry?
I still have this issue on the Legacy 13.1 drivers on Ubuntu 12.04, HD 3870. Has anyone reported it to AMD?
Sorry, I don't know if this has been reported. I did not.
I am afraid that AMD doesn't really care about their "Legacy" driver : version 13.1 only works with X.org <= 12 and with an old kernel version. Personally, I use open source drivers now. Even if performance is bad, and some games are buggy (some GL extensions are lacking), these drivers are offering better compatibility with recent systems, and are constantly improving.
Closing as general video driver quality from 2013 is no longer relevant.
Hello,
I Have a segmentation fault when I try to launch big picture mode.
I have an ATI Radeon HD 4850 with 13.1 legacy drivers.
Terminal output (I tried to translate) :
Backtrace :
I can provide you more information if you would like.
