Summary0002520: r7905 crashes when no -keyboard_layout is specified
Descriptionr7905 introduced the new -keyboard_layout option. However, when not specified, it causes strcmp to be called on a null pointer, which causes a segfault on my system/optimizations (Linux x86_64)
Additional InformationRecommend to first check if the option is specified before running strcmp.

Please see attached patch.
