[pkg-uWSGI-devel] Bug#901774: Crash on SIGQUIT with plugin-python3

[wavexx]

Package: uwsgi-plugin-python3
Version: 2.0.17.1-8
Followup-For: Bug #901774

I'm afraid to report that although since 2.0.17.1-6 it's rarer, I do
still get crashes during shutdown/reload/sigquit in uwsgid.

The stack trace is similar too, just less likely to happen:
