Comment #2 is bug 347344.
Still crash on exit in KDE Plasma 5.5.3 with Qt 5.5.1: https://bugs.kde.org/show_bug.cgi?id=357718#c1
Martin, can you reproduce since bug 347344 was fixed? It might have been the same cause.
as I switched the windowing system I'm not sure whether me testing it, still makes sense. But here it crashed, though with different backtrace, which I cannot paste because copy'n'paste between X11 (Firefox) and Wayland (Yakuake with gdb output) is not yet implemented. It was a crash from KIconLoader.
I can't reproduce with with Network Interfaces or the Energy Information. I would assume it to be fixed.
Assuming it was caused by the same solid <-> qml connections. If you still get a KInfoCenter crash, please report a new bug. *** This bug has been marked as a duplicate of bug 347344 ***
