intermittent test failure: qa_pcbnew crashes
Description
the qa_pcbnew test has started to fail intermittently, somewhere between 9fb05440b3 and 6.0.0-rc1
latest failure
the "/homeless-shelter permission denied" errors are due to build sandboxing by Nix

that also shows the error didn't occur before updating to 6.0.0-rc1
i've done some bisecting, as the failure is intermittent i used a longer duration of the qa_pcbnew test as an indicator
that ended up with this
There are only 'skip'ped commits left to test.

We cannot bisect more!(maybe not entirely resolved?)

Steps to reproduce
- run
