On Ubuntu 17.10, with KDE 5.12.0 : When in System Settings / Shortcuts, clicking on Web Shortcuts, then on Custom Shortcuts crashes System Settings.
Pastebin of the backtrace (not useful according to KDE, but I thought that maybe it could be of some help !) https://privatebin.net/?776cb2449458b334#rT3o+Lm1jZT+uiZuMh25LeCtp64lJt2bTJ3n8ZHO2o0=
