I've been having same problem.
It doesn't seem to happen with 5.1.1, so it's probably related to recent changes to qwindowskeymapper.

it usually happens when you press space or enter while typing Korean.

Hi,

This looks like a bad bug. Please report it at http://bugreports.qt-project.org/

Anyway, what happens if you click "Ignore (I)"? There is a chance the program can still run. Asserts don't happen in Release mode.

Is there any workaround for this problem?

One of the ways to avoid assert/crash is to:
Type in additional characters and then use backspace to remove those extra characters.

Assert/crash seems to occur when you input spacebar or enter while IME is composing a Korean character (which is composed of anywhere between 2~5 key inputs)

This workaround is okay for developer himself, but if you're planning to release your software to others you'll need to use Qt 5.1.1 until this issue is resolved.
