Fix crash

Lyx crashes on export to pdf if used with sanitizer set to 'unspecified'.
Crash found by Scott.

Given that if we export without GUI, there is some weirdness here though.
1.) Why does lyx not crash if not using '-fsanitize' compile-option
2.) Why is export to pdf dependent on the screen-resolution
