  The problem is ```realLine >= m_renderer->doc()->lines()``` it return a nullptr. First of all https://phabricator.kde.org/source/ktexteditor/browse/master/src/render/katelayoutcache.cpp;ad51cece443bc6bb643fa4ca94293a13d3c2f852$368 should be checked against nullptr, even all other places that line(..) is used or better handling of corner case.
