Just tried, Quassel and trojitá (latter uses QSystrayIcon + QPA) actually \
work with the present code. (Not checked details, but apparently \
minimizeRestore isn't invoked anyway??)
Trying amarok later (requires complete update for new libav deps) but would \
like to express my greatest disgrace for systrays in general and SNI in \
particular. The SNI daemon silently quit (not killing kded!) several times! \
during the tests and I spent 5 minutes just to figure why I suddenly wasn't \
getting any tray icon and associated widgets turned 0x0 ... this entire \
thing is seriously far too fragile to be useful. *grrrr*
