I have to use Skype and can't see its tray icon after update from plasma-workspace-4.11.17 to plasma-desktop-5.2.1. See details here: http://blog.martin-graesslin.com/blog/2014/03/system-tray-in-plasma-next/ Related bug/wish: bug#344168 Reproducible: Always
Please report against your distribution to provide the required packages I mentioned in my blog post.
OK, already figured it out. Thanks! Downstream bug report: https://bugs.gentoo.org/show_bug.cgi?id=516162 It's on its way to getting fixed in Gentoo, but there is still some work left to do unless you want to rebuild half of your system. Because sni-qt[abi_x86_32] is not happy with app-emulation/emul-linux-x86-qtlibs (see https://bugs.gentoo.org/show_bug.cgi?id=516488#c8 -> comment #8) and pulls qt*[abi_x86_32] instead, you have rebuild qtcore, qtgui, qtdbus and all their dependencies for both ABIs. (Of course only if you have a x86_64 system.)
