Crash with KiCAD 7 on macOS running plugin

[Daniel O'Connor]

Hi,
I've been working on updating this plugin https://github.com/Bouni/kicad-jlcpcb-tools to work with v7 and also to get the JLC parts from a different place (see https://github.com/DanielO/kicad-jlcpcb-tools/tree/csv-creation) however I have noticed it has a tendency to crash while downloading the file.

Unfortunately I am not really sure what triggers it. It happens while the download process is running (which is a streaming http request -> LZMA decode -> CSV parse -> sqlite DB write) but not at the start or the end...

I haven't tried building KiCAD locally but probably could if patches need testing.

Thanks.

Below is the crash reporter output:
