Importing

[stefanadelbert]

Blender crashes when I attempt to import the example project.

$ blender
Read prefs: /home/stefan/.config/blender/2.82/config/userpref.blend
Warning: property 'release_confirm' not found in keymap item 'OperatorProperties'
Writing: /tmp/blender.crash.txt
Segmentation fault (core dumped)

If I deselect Import background image then the import succeeds.

Linux 4.19.118-1-MANJARO #1 SMP Thu Apr 23 10:54:30 UTC 2020 x86_64 GNU/Linux blender 2.82a fSpy 1.0 3

Thanks for this report! It would be interesting to have a look at the project you're trying to import and the /tmp/blender.crash.txt log file.

This is what /tmp/blender.crash.txt looks like after attempting to import the fSpy example project:

I've just noticed that if I manually add the background image corresponding with an fSpy project, I get a crash too.

[stuffmatic]

Does blender crash for other images? Or just one? Would you mind sharing the image that's causing the crash?

[stefanadelbert]

• If I attempt to import the same image into a default blender project, there is no issue.
• If I import the fSpy project (with Import background image deselected) and then load the image manually, then blender crashes.
• If I import the fSpy project (with Import background image deselected), untick the tick next to Object Data Properties | Background Images and then load the image manually, then I get the image loaded ok and all good!

Something fishy about Background Images being ticked when Import background image is deselected on import. But then what do I know!

I see the same issue when using the example fSpy project and can recreate with that. I can also recreate the issue by importing any JPEG image after importing an fSpy project with Import background image deselected.
