I just upgraded my Gentoo system (latest GLibc, GCC) and Kate now crash on load. This is due to the plugin system failing to load the project plugin. I looked around and no left-over file seem to be present. For now, I patched it using void KatePluginManager::loadPlugin(KatePluginInfo *item) { /** * try to load the plugin */ if (item->saveName() != QLatin1String("kateprojectplugin")) item->load = (item->plugin = KPluginLoader(item->metaData.fileName()).factory()->create<KTextEditor::Plugin>(this, QVariantList() << item->saveName())); /** * tell the world about the success */ if (item->plugin) { emit KateApp::self()->wrapper()->pluginCreated(item->saveName(), item->plugin); } } Reproducible: Always Steps to Reproduce: 1.
