gdb trace reproducing krita crash with debug info fetched with debuginfod

Exporting a L*A*B* colorspace document to webp crashes krita and does not save the image. Reproducible on my system.

Not Working: 
1. Open Krita
2. Click "New Image"
3. Input the Image Size and Color settings for a 128x128 L*a*b*/Alpha 8-bit integer/channel document.
4. Click "Create"
5. Click "File"
6. Click "Export"
7. Input any filename that ends with .webp and click "Ok" on the default webp export settings.
8. Crash

Working:
1. Open Krita
2. Click "New Image"
3. Input the Image Size and Color settings for a 128x128 RGB/Alpha 8-bit integer/channel document.
4. Click "Create"
5. Click "File"
6. Click "Export"
7. Input any filename that ends with .webp and click "Ok" on the default webp export settings.
8. The file gets saved and krita does not crash.

Additionally:
Tested the flathub 5.2.3 version, same result
Tested the krita-5.2.5-prealpha-4e96fd2674-x86_64.appimage version, same result
The gdb trace should have debug info automatically fetched with debuginfod

I can confirm the issue. Something goes wrong when converting the image to rgb (which is necessary, because webp doesn't support lab).
Comment 2 Halla Rempt 2024-08-04 08:24:30 UTC 
For some reason the destination colorspace object is 0:
