The OktetaPart plugin is used in another application (Krusader) and it crashes on the second call of openUrl(). Here is the test code:

      KPluginLoader loader("oktetapart");
      KPluginFactory *factory = loader.factory();
      KParts::ReadOnlyPart* part = factory->create<KParts::ReadOnlyPart>(this, this);
      part->openUrl(url1);
      part->openUrl(url2); // crash here


And the stack trace:
