Ok, I could find new recipy for the crash in old master (50% probability) and
could not make it crash after updating to the current master (354d319a5d) with ~20 trials.
Probably best we can get.

If you wanted to understand the original cause, this is the new recipy for the master,
you could try to reproduce one more time:

checkout the commit 8a181862d
0) load the file I sent you earlier
1) set cursor on line 1.4
2) scroll 1.4 it to be the last line of the screen
3) close lyx
4) remove figure cache
5) relaunch lyx & wait for figures on screen to load
   if not crash goto 2 

Once you get crash, you have longer serie of crashes with the above recipy  (like order of 3-6)
Once it survives, you have longer serie of ok loads with the above recipy (like order of 2-5) 
In total it averages to about 75% of crash cases.
