Summary:
`kget` followed by clicking in the Notification tray to show the window (if the command line didn't already try to show the window) results in a SIGSEGV.
running `QT_QPA_PLATFORM=xcb kget` avoids this issue.
Initially, the plasma notification was pointing to inabillity to load libmms, so I installed `libmms` from the repos, but the SIGSEGV never really went away. After installing:

It's quite apparent that the `this` pointer is invalid, so I'm not sure if this libmms optional dependency is a red herring.

https://bugs.kde.org/show_bug.cgi?id=463476 is about an optional plugin, this doesn't relate to your crash at all.
