Either we should stop passing bad data to kservice, or kservice should return a real answer instead of crashing when given bad data ("No, this invalid data is not an application"). Probably both, but fixing KService seems more important. Moving to KService.
IIUC, the crash here happens because AppEntry::actions() calls isApplication() on a nullptr, the issue is why/how did m_service become null in AppEntry.
