Adding --enable-debug for configure would help to produce more informative
output (we should see line numbers in the backtrace then).

In this particular case, though, I expect better backtrace won't help
that much. What would be way more useful is if you try to spend some
time and narrow down exact recipy how to reproduce the crash.

The backtrace show it's related to drawing stuff when rendering
math grid, parhaps with some combination with scrolling around
etc. So whenever crash happens, try to reload affected document
and try to redo the last steps, that might give reproducible steps.
