SUMMARY
***
Adding a "Palettize" filter layer and saving the file makes krita freeze after trying to open said file.
Some observations:

***


STEPS TO REPRODUCE
1. Open Krita
2. add a "Palletize" Filter Layer
3. Save the file as .KRA file
4. Close Krita
5.Re-Open Krita
6.Try to open the .KRA file previously saved

OBSERVED RESULT

 - Krita keeps loading the file without ending, window name appears with (not responding)
- this state goes for a long time (up to an hour, might be even more) until you click on the window wich will make Krita freeze and make windows ask to force it to close

EXPECTED RESULT
- The file is loaded without issues in a short amount of time

SOFTWARE/OS VERSIONS
Windows: Windows 10


ADDITIONAL INFORMATION
- Krita only freezes and crashes AFTER the file is saved and said file is tried to be open. There is no issues while working on the same session where the filter was aplied and saved.
- It has been seen that it is only needed a single palettize filter layer to make the file ubable to open again even with one paint layer or no other layer at all, the canvas is as little as 100px in the testings made
