--- Comment #1 from Martin Flöser <mgraess...@kde.org> --- Analysis: the crash is triggered because of showing the Tooltip. from updateDecoration a new internal window is opened which causes update to be called again and m_internalWindow getting reset. Due to that the m_internalWindow becomes null, although the check before evaluated to not null. -- You are receiving this mail because: You are watching all bug changes.
