Created attachment 71557 [details] Patch v2 Ouch, forgot the destructor. SVGPropertyTearOff does it right, SVGListPropertyTearOff also needs to delete m_values if m_valuesIsCopy=true. The code is yet unused, when I convert SVGStringList to use this new code, I would have noticed it on a leaks run...
