The API allows us to report errors by overriding the errorString() method on QQuickImageResponse to return a non-empty string. However, if I do so the application crashes. Loading up the symbols to get a stack trace shows this to be a bug in the logic of QQuickPixmapReader::asyncResponseFinished: QQuickTextureFactory *t = 0; QQuickPixmapReply::ReadError error = QQuickPixmapReply::NoError; QString errorString; QSize readSize; if (!response->errorString().isEmpty()) { error = QQuickPixmapReply::Loading; errorString = response->errorString(); } else { t = response->textureFactory(); } mutex.lock(); if (!cancelled.contains(job)) job->postReply(error, errorString, t->textureSize(), t); mutex.unlock(); If errorString() is not empty, then t will still be NULL. It is then dereferenced to call t->textureSize() resulting in a segfault.
