Comment 6 RJVB 2018-11-25 16:47:54 UTC 
What's the status of this?

I'm seeing very similar crashing during concurrent project reloads, i.e. when a file change triggers a reload of (part of) the project tree that is already being loaded.
I thought such concurrent reloads were possible only because I'm using a patch that modifies the dirwatching protocol to watch directories only but apparently the can occur with stock code too?
Comment 7 Justin Zobel 2020-12-17 05:39:04 UTC 
Thank you for the crash report.

As it has been a while since this was reported, can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved.

I have set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved/worksforme" when you respond, thank you.
Comment 8 ok 2020-12-17 05:54:42 UTC 
I do not have this setup any longer, think it should be reopened if found again.
