Memory segmentation fault

[eivijoha]

I'm experiencing an issue with my brand new Raspberry Pi Camera module 3.

This is with a Raspberry pi 3 model B v1.2 which has been trucking along with earlier camera module and Raspbian Jessie and raspistill for many years.

With the new camera in place an upgrade to Bullseye and picamera2 for the new camera module.

I've done several reinstalls of Bullseye (64 bit) on two differen known good memory cards, updated and upgraded through apt and tried running this really short capture script. This results consistently in a Memory segmentation fault (Minnesegmentsfeil in Norwegian).

Capture script:
`#!/usr/bin/python3

from picamera2 import Picamera2

picam2 = Picamera2()
picam2.start_and_capture_file("test.jpg")
`

Results in this output:
pi@raspelapse:/var/www/html/script $ ./test.py [0:04:27.395370303] [804] INFO Camera camera_manager.cpp:299 libcamera v0.0.2+55-5df5b72c [0:04:27.533132366] [805] WARN RPiController controller.cpp:43 This format of the tuning file will be deprecated soon!

I'm hence unable to capture anything with picamera2 (I've tried enabling legacy support for the old camera module, and the error persists regardles of camera type).

Help? It might be that this should be a bug-report, but trying to find any sources of error first.

I can't be sure, but seeing your locale (Minnesegmentsfeil) makes me think it might be an issue we've resolved but not yet included in a release.

https://git.libcamera.org/libcamera/libcamera.git/commit/?id=e8ae254970cfdeb1b5aba307a95a3189b09c9784

I see you're running libcamera version v0.0.2+55-5df5b72c - so I don't think you'll have this fix.

Thank you, not setting the locale to nb_no fixed the segmentation fault which in turn left me hanging with the Thread-2 hanging bug due to my setup being lite and headless. My solution seem to be using libcamera-still directly (which is what I probably should have started with anyway).
