Please fill out the issue template.

Edit: sorry, didn't read the full title to see you're new to English.

To my understanding, Gulim is the default font in Korean Windows (https://forum.qt.io/topic/14394/solved-qt-text-rendering-issue-on-windows-xp-korean-version). @leesnagjun, can you confirm?

Judging from the traceback, Qt apparently doesn't guarantee that the default font family (as returned by QFont().family()) actually exists in the font database (QFontDatabase().families()).
