Comment 1 Nate Graham 2020-11-20 19:47:37 UTC 
Scary backtrace entirely in Qt and other upstream software. :( No idea what to do with it.
Comment 2 Patrick Silva 2020-11-21 13:20:45 UTC 
I think that this crash was caused by my damaged hard disk. :(
Let's close this report.
Comment 3 Patrick Silva 2021-01-02 13:58:02 UTC 
I have replaced my damaged hard disk with a SSD and this crash is still 
happening on neon unstable.
