VLC segfault / general protection error on start

[silentplummet]

Hello, I am having trouble getting VLC to run on my system. I emerged it normally through portage with no odd use flags, compiler optimizations or kernel modules (beyond the ATI fglrx binary blob). My system is 100% stable in all aspects and runs all the other software I have installed (including mplayer etc). I don't even know where to begin troubleshooting this as I have never experienced a similar problem before and google/forum searches have turned up nothing.

My system is:

Intel Core i5-2500K
4.00 GB DDR3-1600 RAM
ATI 5770
xorg/gnome


Here is the output on the console when I run vlc:

Code: Select all

murasaki ~ $ vlc
VLC media player 1.1.7 The Luggage (revision exported)

... and the following appears in dmesg:
