--- Comment #2 from Fabian Vogt <fab...@ritter-vogt.de> --- I debugged this a bit. The reason this fails is because the call to QIcon::setFallbackThemeName causes QIconLoader::ensureInitialized to be called, which sets up the internal configuration. At this point, however, the platform theme is not yet loaded to m_system_theme is empty. By commenting out the call, the QIconLoader is only initialized after the platform theme got loaded and it works as expected. -- You are receiving this mail because: You are watching all bug changes.
