[meta-freescale] core-image-weston - multiple displays segfault?

[randy.krakora at freescale.com]

Here's what I've gotten so far:

Core was generated by `weston --tty=1 --use-gal2d=1 --use-gl=0 --device=/dev/fb0,/dev/fb2'.
Program terminated with signal SIGSEGV, Segmentation fault.
#0  0x76f0dc00 in wl_resource_post_event ()

No backtrace, please add debug symbols and check where it fails.
