 See here: the factories  size is zero!

Do you have the plugin Qt4ProjectManager enabled?

    QList<QtVersionFactory *> factories = ExtensionSystem::PluginManager::getObjects<QtVersionFactory>();
    qSort(factories.begin(), factories.end(), &sortByPriority);

    foreach (QtVersionFactory *factory, factories) {
        BaseQtVersion *ver = factory->create(qmakePath, &evaluator, isAutoDetected, autoDetectionSource);
        if (ver) {
            ProFileCacheManager::instance()->decRefCount();
            return ver;
        }
    }
    ProFileCacheManager::instance()->decRefCount();
    return 0;
}

I fixed the crash because Creator can't get a valid qt version from system, but it real exist there. both on Windows and Linux.
I try to look into it, but I can't fix the problem. It's so hard to me.
It's only a special issue for me? or for everyone?
It only happened recently.
I have not enought time to figure out what's wrong. e.g. using 'git bisect'. sorry.
So I just want remind it on the list.
