--- Comment #1 from Kai Uwe Broulik <k...@privat.broulik.de> ---
Crahsed in/caused by WindowedWidgetsRunner:
WindowedWidgetsRunner → Plasma::PluginLoader::listAppletMetaData →
KPackage::PackageLoader::loadPackageStructure → KPluginLoader::forEachPlugin →
KPluginMetaData::KPluginMetaData → QPluginLoader::QPluginLoader →
QPluginLoader::setFileName → ... QFile cleanup stuff → boom.
Do we have a concurrency issue here?
