Bug report

Blender 2.93.4

What is the current behavior?

When trying to render headless from the command-line, blender crashes immediately

Also: PowerSequencer crashes blender when you try to deactivate it

What is the expected behavior?

The headless rendering should just proceed

Deactivation should just deactivate the addon

Tell us the steps to reproduce the bug, and if possible share a minimal demo of the problem.

From a blank startup-file go to edit->preferences->addons - locate Power Sequence. Disable it - blender crashes (without disabling it) - in /tmp/blender.crash.text the output is

Any scene I try to render from commandline gives this error

Have you tried 2.93.5? It might be a Blender-side bug in 2.93.4 because I can't reproduce the issue with the latest bugfix version.

[acebone]

I don't know what was at play. All of a sudden I could de-register (and re-register) with no problems, and I can also render from commandline now. It does the render and then it says:

Exception in module unregister(): '/home/esm/.config/blender/2.93/scripts/addons/VSEQF-master/init.py' Traceback (most recent call last): File "/home/esm/src/blender/blender-2.93.4-linux-x64/2.93/scripts/modules/addon_utils.py", line 438, in disable mod.unregister() File "/home/esm/.config/blender/2.93/scripts/addons/VSEQF-master/init.py", line 1608, in unregister keymapitems = bpy.context.window_manager.keyconfigs.addon.keymaps['Sequencer'].keymap_items KeyError: 'bpy_prop_collection[key]: key "Sequencer" not found'

Blender quit

However the render is just fine

Something seems to be amiss, but I'm not sure where the fault is exactly.

[NathanLovato]

Could you please try to update to the latest Blender bugfix version? If that addresses the issue, then it's not a bug on the side of power sequencer and we can close this.

[acebone]

Will do ASAP ...

No update since last year, closing the report as we can't reproduce the issue
