Find out why it terminates - get core dump, run in gdb (if there is really no
crash dialog, which is rather unusual).

$ gdb kwin
(gdb) run --replace
(And later 'kwin --replace' e.g. from Alt+F2 to prevent focus problems without
kwin running. The same way, you want to run the gdb not in the same X session
to avoid focus problems.)

'export KDE_DEBUG=1' should make KDE apps normally dump core in case of a
crash.

Running in gdb can tell.

Not with non-debug builds, and even then it'd be unlikely to provide any
useful information.

This doesn't seem to be kiosk related at all. Please normally create a
bugreport at bugs.kde.org.
