ERC: running twice leads to crash

Description

When running the ERC twice on a schematics that includes a rule area, Kicad reproducibly crashes under some conditions.

Steps to reproduce

With the attached schematics, run ERC. This rightfully reports some violations.
Move the +5V power symbol (even just start moving it with g and aborting seems to be enough).
Run ERC again. On my end, this reproducibly leads to a crash.

This is the observed backtrace:
