EESchema — Segmentation fault when previewing footprint in assign tools

[Antoine Pintout]

EESchema : When assigning footprints to symbols, and the footprint preview is open, a segmentation fault occurs.

Steps to reproduce :
– Create a new KiCad project
— Open EESchema
— Place two LEDs
– Launch assign tool
— Launch footprint preview
— Assign two footprint to the symbols or change filtering options :
— KiCad should crash with :
Thread 1 "kicad" received signal SIGSEGV, Segmentation fault.

I can recreate this on the most recent master commit. The error is:

Thread 1 "kicad" received signal SIGSEGV, Segmentation fault.
0x00007fffcb2d47a6 in BOARD_ITEM::GetBoard (this=0x75343e0) at /home/imcinerney/Documents/kicadDev/kicad-master/pcbnew/class_board_item.cpp:72
72 return parent->GetBoard();

The backtrace leading to this is attached.
