QTextControlPrivate::inputMethodEvent() crash

cursor().block().layout() returns null leading to crash. This occurs in context, where I have TextEdit QML element shown on top of PageStack (from qt-components). Inserting/removing text to editor may cause a page change. Page change related to removal of the last character from editor leads to condition where layout() is null. Call stack is provided below.

void QTextControlPrivate::inputMethodEvent(QInputMethodEvent *e)
{
..
bool isGettingInput = !e->commitString().isEmpty()
