from_jpeg - Segmentation fault at 0x0000000000000000 #16

This seems related to some of the other JPEG issues that have been posted before: https://github.com/willglynn/ruby-zbar/issues/5 https://github.com/willglynn/ruby-zbar/issues/2 https://github.com/willglynn/ruby-zbar/issues/15

I'm seeing a seg fault when calling from_jpeg on Zbar::Image which causes the Ruby process to crash. Oddly enough zbarimg at the command line works fine. I'm using zbar 0.10 on the Amazon Linux AMI.

I can personally workaround this for now, but figured I'd mention it.

@etobia I'm hitting this; how did you work around it?
