SUMMARY
Attempting to edit text when you close the text box re-opens it, how ever it makes an error message pop up twice with the only options to ignore (which makes the program impossible to use, as nothing functions) or to abort, which shuts down the entire program with no option of saving your file. 

STEPS TO REPRODUCE
1.Use the text tool to write anything
2.Hit 'save' and 'close'
3.Double click it to re-open text tool

OBSERVED RESULT
An error message reading 
""Krita has encounterd an internal error:

I use Krita via steam. The specific canvas size I was using when I found this issue was 2018x1152 and while I doubt it has any affect I was using the font "Lemon"
