Bug ID: 478341
Summary: Errors trying to run "Hello World" in Scripter
Debugger
Classification: Applications
Product: krita
Version: unspecified
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: Scripting
Assignee: krita-bugs-n...@kde.org
Reporter: gecko...@gmx.de
Target Milestone: ---
Krita 5.2.2 (can't select this version in the bugtracker), Windows 10 64 Bit
This simple script runs fine when pressing the "Run" button.
print("Hello World")
But pressing the "Debug" button instead results in two error dialogs popping
up.
Dialog 1
