I've just came home, and decided to upgrade Plasma. After upgrade, I've connected second monitor (don't know if this is important) and decided to change some settings. And... Settings app does not launched. Windows appearing, nothing in there, then it is closing. Crash dialog does not appearing. Strange, isn't it? Running it from Konsole - oops, Bus error (core dumped). I don't know location of the core dump, if you can help me, I will be glad to upload it. Reproducible: Always Steps to Reproduce: 1. $ sudo yaourt -Syu 2. (maybe) Connect second monitor 3. Launch systemsettings5 Actual Results: Bus error (core dumped) Expected Results: Cute windows to adjust my settings, of course! Archlinux, PC: HP Pavillion dv7-3129er, 4GB RAM, KDE of last version, having installed some software from AUR (git versions of breeze, yaourt and something). SDDM as a display manager (it's really cool with Plasma theme).
Sorry for ignoring this, but this report contains no information to do anything with and now it's too late. Hope you found this got fixed.
