Frame #9, (inside ResourceHandler::updateResourcesHelper): project->rootProjectNode() returns null here:
// Find the (sub-)project the file belongs to. We don't want to find resources
// from other parts of the project tree, e.g. via a qmake subdirs project.
Node * const fileNode = project->rootProjectNode()->findNode([&fileName](const Node *n) {

Before the 22da0f2fd660ebd916a140d1d3a64632bca7cc35 change, the
Project *project = SessionManager::projectForFile(Utils::FilePath::fromUserInput(fileName));
returned nullptr, now it returns non-nullptr for which project->rootProjectNode() returns null.
