Akregator exits even if the exit confirmation dialog is canceled or closed through the window manager. Basically, once the exit confirmation dialog is displayed, exiting Akregator is a certain outcome. This may well be a (silent) crash. Here's what's printed on the console after closing the exit confirmation dialog in any way (even with OK): akregator(12973)/kdecore (KConfigSkeleton) KCoreConfigSkeleton::writeConfig: akregator(12973)/kdecore (KConfigSkeleton) KCoreConfigSkeleton::writeConfig: akregator(12973)/kdeui (kdelibs) KXMLGUIClient::~KXMLGUIClient: 0x1a9d7f0 deleted without having been removed from the factory first. This will leak standalone popupmenus and could lead to crashes. akregator(12973)/kdeui (kdelibs) KXMLGUIClient::~KXMLGUIClient: 0x171a420 deleted without having been removed from the factory first. This will leak standalone popupmenus and could lead to crashes.
Appears fixed in 4.9 (I am the original reporter).
