Problem Description

Spyder starts, the IDE shows briefly, then Spyder segv’s and closes 3-5 seconds later, before the kernel finishes starting. No information is reported at the console other than:

Segmentation fault (core dumped)

I can run qtconsole from the command line (i.e., jupyter qtconsole), and it starts normally.

spyder --reset runs (including the splash screen) and terminates normally.

Versions

• Spyder version: 4.1.2
• Python version: 3.7.7
• Qt version: 5.6.0
• PyQt version: 5.6.3
• Operating System name/version: Ubuntu 16.04

Qt and PyQt were rolled back to 5.6.* in this case from the current 5.9 versions because of the “Could not initialize GLX” error. I don’t think this is related to the present issue, since the IDE shows for a few seconds before the segv in this case.

Let me know what else I can provide to help debug! Thanks.

NP, I consider this fixed for me; Spyder 4 works everywhere except for one archaic machine where Spyder 3 works fine. I call that a win! Thanks for your quick responses…

I do all my dev in Spyder and have since I picked up Python, I’m a super-fan!

Thanks.
