I was saving a .kra file with a layer that was created with the option of "open file" when I had no others layers (new project), the file I opened was a jpeg.



Reproducible: Sometimes

Steps to Reproduce:
1) Open Krita
2) File>Open file> a *.jpeg file
3) File>Save as *.kra
4) it says is saving, I check the saving folder and it has the *.kra file with something like this *.kra(1 letter)(five numbers).new, and never stops to say it's saving.
4a) Modify the layer in somethin, paint over it
5) Then File>Save or File>Save as...
6) Crash
7) I check again the folder, and creates another file like *.kra(1 letter)(five numbers).new but now empty
8) Krita says the archive created in steps 3), 4) is corrupted

Actual Results:  
Crash + one corrupted .kra file + one empty .kra file both with weird names

Expected Results:  
one fine .kra file

Workaround

I create the project with File>New with the resolution I have the *.jpeg, I import the *.jpeg instead with Layer>Import/Export>Import>Import Layer and then It saves in the normal way (1 second to save or so, and uncorrupted)
