Another segfault in the stable branch involving previews (and master as
well). When Instant preview is on and one copies a formula, it randomly
crashes. In the attached, select the math inset and hold Ctrl+C until it
segfaults. Sometimes it happens on the first press. This is pretty
annoying because it's not a corner case at all. There is a very simple
math macro, but it does not crash with preview off.
The positive side is that I am getting a glimpse that having instant
previews that actually work is very pleasing :)

Does not take cd046f0e into account. Let me test again.
Still there at cd046f0e (master). But here's the trace I get when it
crashes right at the first Ctrl+C:
