^ dialog with the error messages.

Hi, 

I can't open a specific Krita kra source file, the one for the book cover #2 of
Pepper&Carrot. I have to mention that the Krita file was decompressed and
recompressed (with a custom bash script based on unzip/zip command line)
manually to save disk space, but this script usually has no impact on my Krita
files and I use it since a big year.  It's also one of my most complex Krita
source file: using many vector layers, filters, layer groups, etc... So, maybe
it is sensitive to something usually hidden.

The file
======
- Preview:
https://www.peppercarrot.com/en/viewer/book-publishing__en_B02_cover_hardcover_72pages_8.5x11_by-David-Revoy.html
- Source:
https://www.peppercarrot.com/0_sources/0ther/book-publishing/zip/en_B02_cover_hardcover_72pages_8.5x11_by-David-Revoy.zip

To Reproduce:
============
Just open the Krita file. 

Result:
======
Krita will display a dialog (screenshot in attachement) with a lot of errors. 
- Could not load pixel data
- Could not load profile 
- Could not filter configuration  → (this line probably misses a 'load' word)
Then, all layers are loaded as transparent pixels.

Observations:
===========
- It's not a regression: I tested with various appimage (from 4.1, 4.2x to
latest 5.1betas-nightly): the result is similar.
- I had a backup of the original Krita file (before recompression) and I could
open it. A dialog just invite to adapt the dpi (a classic from Krita 4 to Krita
5 files). 
- The bug was discovered by Ondrej on
https://framagit.org/peppercarrot/book-publishing/-/issues/7 , I'll give him
the fixed backup file so he is not blocked into publishing the German book of
Pepper&Carrot #2. 

All in all, I thought this case could be interesting. 
If it is just related to the zip/unzip data recompression that broke the file,
I'll totally understand to blame zip.
