In release mode, the stack trace is unhelpful, but in debug, it's:

ASSERT(count > m_partialSequenceSize);

 -> WebCore::TextCodecUTF8::decode(char const*, unsigned long, bool, bool, bool&)
 -> WebCore::TextEncoding::decode(char const*, unsigned long, bool, bool&) const
 -> WebCore::TextEncoding::decode(char const*, unsigned long) const
 -> WebCore::decodeURLEscapeSequences(WTF::String const&, WebCore::TextEncoding const&)
 -> WebCore::decodeURLEscapeSequences(WTF::String const&)
 -> WebCore::(anonymous namespace)::decodeURL(WTF::String const&, WebCore::TextEncoding const&)
 -> WebCore::XSSFilter::init()
 -> WebCore::XSSFilter::filterToken(WebCore::HTMLToken&)
 -> WebCore::HTMLDocumentParser::pumpTokenizer(WebCore::HTMLDocumentParser::SynchronousMode)
