I have an ATI graphics card, using the ATI Catalyst fglrx proprietary drivers, and have the same problem.

vlc was crashing after call va_getDriverName():

Segmentation fault

Setting the LIBVA_DRIVER_NAME environment variable to **anything** fixes the crash, even if it's not a valid driver name (e.g. "fred"):

Setting LIBVA_DRIVER_NAME to "fglrx", and ensuring that /usr/lib/dri/fglrx_drv_video.so is linked to /usr/lib/va/drivers/fglrx_drv_video.so allows VLC to use the fglrx driver
