Random crash in Linux

[xgouchet]

Hey, so I'm using the latest version of ReText (commit 0c605f9), and I get random crashes while typing.

I'm running on Linux, with Python 3.8.10, with live preview enabled with Chromium renderer, and get the following crash logs:

Do you know when it started crashing? Was it after upgrade of ReText, upgrade of Qt WebEngine or some other libraries?

I see there are at least 9 processes. Is that because you have 9 tabs open? Does it happen with smaller number of tabs too?

Also maybe you can try to obtain a stack trace by running Python in gdb?

[xgouchet]

Yes I did have several tabs opened (9 seems correct). IIRC it did happen with only 4 or 5 tabs opened. And before I used to be able to have 20 tabs opened on the same laptop without any issue.

It only happened since I updated to the latest version, before I was on the 7.2.0 exactly and didn't have any issue. I'll try and use gdb next time I get the chance.
